SFA-5.28/SFA-5.28M

(Identical with AWS Speci?cation A5.28/A5.28M:2005.In case of dispute,the original AWS text applies.)

1.Scope

1.1This speci?cation prescribes requirements for the

classi?cation of low-alloy steel electrodes(solid,compos-

ite stranded and composite metal cored)and rods(solid)

for gas metal arc(GMAW),gas tungsten arc(GTAW),

and plasma arc(PAW)welding.

1.2Safety and health issues and concerns are beyond

pthe scope of this standard and therefore are not fully

addressed herein.Some safety and health information can

be found in the nonmandatory Sections A5and A10.Safety

and health information is available from other sources,

including but not limited to ANSI Z49.1,Safety in Welding,

Cutting,and Allied Processes,and applicable federal and

state regulations.

1.3This speci?cation makes use of both U.S.Custom-

ary Units and the International System of Units(SI).The

measurements are not exact equivalents;therefore,each

system must be used independently of the other without

combining in any way when referring to weld metal proper-

ties.The speci?cation with the designation A5.28uses U.S.

Customary Units.The speci?cation A5.28M uses SI Units.

The latter are shown within brackets[]or in appropriate

columns in tables and?gures.Standard dimensions based

on either system may be used for sizing of electrodes or

packaging or both under the A5.28or A5.28M speci?ca-

tions.

employed,and the results required are given in Sections

9through13.See Section A4.2in the Annex for require-ments for classi?cation based on gas tungsten arc welding (GTAW)only.

7.2The optional test for diffusible hydrogen in Section 14,Diffusible Hydrogen Test,is not required for classi?ca-tion.See Note(a)of Table5.

8.Retest

If the results of any test fail to meet the requirement, that test shall be repeated twice.The results of both retests shall meet the requirement.Specimens for retest may be taken from the original test assembly or from one or two new test assemblies.For chemical analysis,retest need be only for those speci?c elements that failed to meet their requirement.If the results of one or both retests fail to

636meet the requirement,the material under test shall be con-sidered as not meeting the requirements of this speci?cation for that classi?cation.

In the event that,during preparation or after completion of any test,it is clearly determined that speci?ed or proper procedures were not followed in preparing the weld test assembly or test specimens,or in conducting the test,the test shall be considered invalid,without regard to whether the test was actually completed,or whether the test results met,or failed to meet,the requirement.That test shall be repeated,following proper speci?ed procedures.In this case,the requirement for doubling the number of test speci-mens does not apply.

9.Weld Test Assemblies

9.1At least one weld test assembly is required,and two may be required(depending on the electrode-solid as

opposed to composite-and the manner in which the sample

for chemical analysis is taken),as speci?ed in Table5. They are as follows:

(a)The groove weld in Fig.1for mechanical properties and soundness of the weld metal for both composite and solid electrodes(see Section A4.2in the Annex for require-ments for classi?cation based on gas tungsten arc weld-ing only).

(b)The weld pad in Fig.2for chemical analysis of the weld metal from composite stranded and composite metal cored electrodes.

The sample for chemical analysis of weld metal from composite electrodes may be taken from the reduced sec-tion of the fractured all weld metal tension test specimen

or from the corresponding location(or any location above it)in the groove weld in Fig.1,thereby avoiding the need

to make a weld pad.In case of dispute,the weld pad in Fig.2shall be the referee method.

9.2Preparation of each weld test assembly shall be as speci?ed in9.3and9.4.The base metal for each assembly shall be as required in Table6and shall meet the require-ments of the speci?cation shown there,or an equivalent speci?cation.Testing of the assembly shall be as speci?ed

in10.2,10.3,and Sections11through13.

9.3Groove Weld

9.3.1For all classi?cations a test assembly shall be prepared and welded as speci?ed in Fig.1,using base metal of the appropriate type speci?ed in Table6,and the preheat and interpass temperature speci?ed in Table7.The electrode used shall be0.045in.or1?16in.[1.2mm or 1.6mm]size(or the size the manufacturer produces that

is closest to one of these,if these sizes are not produced). See Section A4.2in the Annex for requirements for classi-

?cation based on gas tungsten arc welding(GTAW)only. Welding shall be in the?at position,and the assembly shall be restrained(or preset)during welding to prevent warpage in excess of5degrees.An assembly that is warped more than5degrees out of plane shall be discarded.Test assemblies shall not be straightened.The test assembly shall be tack welded at or above room temperature and welding shall begin at the preheat temperature speci?ed in Table7.Welding shall continue until the assembly has reached the interpass temperature speci?ed in Table7, measured by temperature indicating crayons or surface thermometers at the location shown in Fig.1.

For the remainder of the weld,the preheat temperature and interpass temperature as speci?ed in Table7shall be maintained.Should it be necessary to interrupt welding, the assembly shall be allowed to cool in still air at room temperature.The assembly shall be preheated to the tem-perature speci?ed in Table7before welding is resumed. When welding has been completed and the assembly has

639cooled,the assembly shall be prepared and tested as speci-?ed in Section11,Radiographic Test;Section12,Tension Test;and Section13,Impact Test.Testing shall be per-formed in the as-welded or postweld heat-treated condition, as speci?ed in Tables3and4.

9.3.2When required,the test assembly shall be post-weld heat treated before removal of mechanical test speci-mens.This postweld heat treatment may be done either before or after the radiographic examination.

9.3.2.1The furnace shall be at a temperature not higher than600°F[320°C]when the test assembly is placed in it.The heating rate,from that point to the holding temper-ature speci?ed in Table7,shall not exceed400°F per hour [220°C per hour].

9.3.2.2The test assembly shall be maintained at the temperature speci?ed in Table7for1hour(-0,+15 minutes).

9.3.2.3When the one hour holding time has been completed,the assembly shall be allowed to cool in the furnace to a temperature below600°F[320°C]at a rate not exceeding350°F per hour[190°C per hour].The assem-bly may be removed from the furnace at any temperature below600°F[320°C]and allowed to cool in still air to room temperature.Testing of the assembly shall be as speci?ed in Sections11through13.

9.4Weld Pad.A weld pad shall be prepared using composite stranded and composite metal cored electrodes as shown in Fig.2,except when,as permitted in9.1,the sample for analysis is taken from the groove weld(Fig.1) or the fractured all weld metal tension test specimen.Base metal of any convenient size which will satisfy the mini-mum requirements of Fig.2,and is of a type speci?ed in Table6,shall be used as the base for the weld pad.The surface of the base metal on which the?ller metal is depos-ited shall be clean.The pad shall be welded in the?at position with multiple layers to obtain undiluted weld metal (4layers minimum thickness).The electrode size shall be 0.045in.or1?16in.[1.2mm or1.6mm]or the size that the manufacturer produces that is closest to one of these, if these sizes are not produced.The preheat temperature shall not be less than60°F[15°C]and the interpass temper-ature shall not exceed that speci?ed in Table7.Any slag shall be removed after each pass.The pad may be quenched in water between passes(temperature of the water not speci?ed).The dimensions of the completed pad shall be as shown in Fig.2.Testing of this assembly shall be as speci?ed in10.2and10.3.The results shall meet the requirements of Table2.

10.Chemical Analysis

10.1A sample of the solid electrode or rod stock from which it is made shall be prepared for chemical analysis.

FIG.2PAD FOR CHEMICAL ANALYSIS OF WELD METAL FROM COMPOSITE

ELECTRODES

ASME2010 5.28

[S NOTES:

1.Base metal of any convenient size,of the type speci?ed in Table 6,shall be used as the base for the weld pad.

2.The surface of the base metal on which the ?ller metal is to be deposited shall be clean.

3.The pad shall be welded in the ?at position with successive layers to obtain weld metal of suf?cient height

4.The number and size of the beads will vary according to the size of the electrode and the width of the weave,as well as with the amperage

employed.

5.The preheat temperature shall not be less than 60°F [15°C]and the maximum interpass temperature shall not exceed that speci?ed in Table 7

6.Any slag shall be removed after each pass.

7.The test assembly may be quenched in water between passes to control interpass temperature.

8.The minimum completed pad size shall be at least four layers in height (H).The sample for analysis shall be taken at least 3?8in.[9.5mm]

above the original base metal surface.The length (L),after allowance for start and stop areas,and width (W)shall be suf?cient to perform analysis.

Solid ?ller metal,when analyzed for elements that are present in a coating (copper ?ashing,for example),shall be analyzed without removing the coating.When the ?ller metal is analyzed for elements other than those in the coating,the coating shall be removed,if its presence affects the results of the analysis for the other elements.10.2Composite stranded or metal cored electrodes shall be analyzed in the form of weld metal,not ?ller metal.The sample for analysis shall be taken from weld metal obtained with the electrode and the shielding gas as speci-?ed in Table 3.The sample may be taken from the weld pad prepared in accordance with 9.4,from an area of the groove weld as speci?ed in 9.1,or from the reduced section of the fractured tension test specimen.In case of dispute,the weld pad is the referee method.

The top surface of the pad described in 9.4and shown in Fig.2shall be removed and discarded.A sample for analy-sis shall be obtained from the underlying metal,no closer than 3?8in.[9.5mm]to the surface of the base metal in Fig.2,by any appropriate mechanical means.The sample shall be free of slag.When the sample is taken from the groove weld or the reduced section of the fractured tension test specimen,that material shall be prepared for analysis by any suitable mechanical means.

641

10.3The sample obtained as speci?ed in 10.1or 10.2shall be analyzed by accepted analytical methods.The referee method shall be ASTM E 350.

10.4The results of the analysis shall meet the require-ments of Table 1for solid electrodes or Table 2for compos-ite electrodes for the classi?cation of electrode under test.11.Radiographic Test

11.1The groove weld described in 9.3.1and shown in Fig.1shall be radiographed to evaluate the soundness of the weld metal.In preparation for radiography,the backing shall be removed and both surfaces of the weld shall be machined or ground smooth.It is permitted on both sides of the test assembly to remove base metal to a depth of 1

?16in.[1.5mm]nominal below the original base metal surface in order to facilitate backing and/or buildup removal.Thickness of the weld metal shall not be reduced by more than 1?16in.[1.5mm]less than the nominal base metal thickness.Both surfaces of the test assembly,in the area of the weld,shall be smooth enough to avoid dif?culty in interpreting the radiograph.

11.2The weld shall be radiographed in accordance with ASTM E 1032.The quality level of inspection shall be 2-2T.

SFA-5.28/SFA-5.28M2010SECTION II,PART C

11.3The soundness of the weld metal meets the require-ments of this speci?cation if the radiograph shows no cracks,no incomplete fusion,and no rounded indications

in excess of those permitted by the radiographic standards

in Fig.3.In evaluating the radiograph,1in.[25mm]

of the weld on each end of the test assembly shall be disregarded.

A rounded indication is an indication(on the radiograph) whose length is no more than3times its width.Rounded indications may be circular,elliptical,conical,or irregular

in shape,and they may have tails.The size of a rounded indication is the largest dimension of the indication,includ-ing any tail that may be present.The indication may be of porosity or slag.Indications whose largest dimension does not exceed1?64in.[0.4mm]shall be disregarded.Test assemblies with indications larger than the largest indica-tions permitted in the radiographic standards(Fig.3)do not meet the requirements of this speci?cation.

12.Tension Test

12.1One all-weld-metal round tension test specimen,

as speci?ed in the Tension Tests section of AWS B4.0 [AWS B4.0M],shall be machined from the groove weld described in9.3.1,and shown in Fig.1,as required in Table 5.The tensile specimen shall have a nominal diameter of 0.500in.[12.5mm]and a nominal gage length-to-diameter ratio of4:1.Other dimensions of the tension test specimen shall be as speci?ed in the Tension Test section of AWS

B4.0[AWS B4.0M].

12.1.1After machining,but before testing,the speci-men may be aged at200to220°F[95to105°C]for up

to48hours,then allowed to cool to room temperature. Refer to A8.3for a discussion on the purpose of aging.

12.1.2The specimen shall be tested in the manner described in the tension test section of AWS B4.0[AWS

B4.0M].

12.1.3The results of the all-weld-metal tension test shall meet the requirements speci?ed in Table3.Test reports shall indicate if the specimen was tested in the aged condition.

13.Impact Test

13.1For those classi?cations for which impact testing

is required in Table5,?ve Charpy V-notch impact test specimens,as speci?ed in the Fracture Toughness Testing

of Welds section of AWS B4.0[AWS B4.0M],shall be machined from the test assembly shown in Fig.1.

The Charpy V-Notch specimens shall have the notched surface and the surface to be struck parallel within0.002 in.[0.05mm].The other two surfaces shall be square with the notched or struck surface within±10min of a degree. The notch shall be smoothly cut by mechanical means and

644shall be square with the longitudinal edge of the specimen within one degree.

The geometry of the notch shall be measured on at least one specimen in a set of?ve specimens.Measurement shall be done at a minimum50times magni?cation on either a shadowgraph or metallograph.The correct location of the notch shall be veri?ed by etching before or after machining.

13.2The?ve specimens shall be tested in accordance with the fracture toughness test section of AWS B4.0 [AWS B4.0M].The test temperature shall be that speci?ed in Table4for the classi?cation under test.

13.3In evaluating the test results,the lowest and the highest values obtained shall be disregarded.Two of the remaining three values shall equal,or exceed,the speci?ed 20ft W lbf[27J]energy level.One of the three may be lower,but not lower than15ft W lbf[20J],and the average of the three shall be not less than the required20ft W lbf [27J]energy level.For classi?cations requiring50ft W lbf [68J],two of the remaining three values shall equal,or exceed,the speci?ed50ft W lbf[68J]energy level.One of the three may be lower,but not lower than40ft W lbf[54J], and the average of the three shall be not less than the required50ft W lbf[68J]energy level.

14.Diffusible Hydrogen Test

14.1For each electrode to be designated by an optional supplemental diffusible hydrogen designator,the0.045in. or1?16in.[1.2mm or1.6mm]size,or the size that the manufacturer produces that is closest to one of these sizes if the speci?ed sizes are not produced,shall be tested according to one of the methods given in AWS A4.3.Based upon the average value of test results which satisfy the requirements of Table8,the appropriate diffusible hydro-gen designator may be added at the end of the classi?cation.

14.2Testing shall be done without rebaking or other-wise conditioning the electrode,unless the manufacturer recommends otherwise.If the electrode is rebaked,that fact,along with the method used for rebaking,shall be noted on the test report.

14.3For purposes of certifying compliance with optional diffusible hydrogen requirements,the reference atmospheric condition shall be an absolute humidity of10 grains of water vapor per pound[1.43g/kg]of dry air at the time of welding.The actual atmospheric conditions shall be reported,along with the average value for the test, according to AWS A4.3.8

14.4When the absolute humidity equals or exceeds the reference condition at the time of preparation of the 8See A8.2(in Annex A).

PART C —MANUFACTURE,IDENTIFICATION,AND PACKAGING 15.

Method of Manufacture

The electrodes and rods classi?ed according to this speci-?cation may be manufactured by any method that will produce electrodes and rods that meet the requirements of this speci?cation.16.

Standard Sizes

Standard sizes for electrodes and rods in the different package forms [straight lengths,coils with support,coils without support,drums,and spools (see Section 18,Stan-dard Package Forms)]are as shown in Table 9.17.Finish and Uniformity

17.1All electrodes and rods shall have a smooth ?nish which is free from slivers,depressions,scratches,scale,seams,laps (exclusive of the longitudinal joint in composite metal cored electrodes),and foreign matter that would adversely affect the welding characteristics,the operation of the welding equipment,or the properties of the weld metal.

646

17.2Each continuous length of ?ller metal shall be from a single heat or lot of material,and welds,when present,shall have been made so as not to interfere with the uniform,uninterrupted feeding of the ?ller metal on automatic and semiautomatic equipment.

17.3The components in composite electrodes (includ-ing the core ingredients in metal cored electrodes)shall be distributed with suf?cient uniformity throughout the length of the electrode so as not to adversely affect the performance of the electrode or the properties of the weld metal.

17.4A suitable protective coating may be applied to any ?ller metal in this speci?cation.Copper may be used as a coating for any classi?cation.

18.Standard Package Forms

18.1Standard package forms are straight lengths,coils with support,coils without support,spools,and drums.Standard package dimensions and weights for each form are given in Table 10.Package forms,sizes,and weights other than these shall be as agreed between purchaser and supplier.

18.2The liners in coils with support shall be designed and constructed to prevent distortion of the coil during normal handling and use and shall be clean and dry enough to maintain the cleanliness of the ?ller metal.

18.3Spools shall be designed and constructed to pre-vent distortion of the ?ller metal during normal handling and use and shall be clean and dry enough to maintain the cleanliness of the ?ller metal.Standard spools are shown in Figs.4A and 4B.

19.Winding Requirements

19.1Electrodes on spools and in coils (including drums and reels)shall be wound so that kinks,waves,sharp bends,overlapping or wedging are not encountered,leaving the ?ller metal free to unwind without restriction.The outside end of the ?ller metal (the end with which welding is to begin)shall be identi?ed so it can be readily located and shall be fastened to avoid unwinding.

19.2The cast and helix of electrode in coils,spools,and drums,shall be such that the electrode will feed in an uninterrupted manner in automatic and semiautomatic equipment.

19.3The cast and helix of solid ?ller metal on 4in.[100mm]spools shall be such that a specimen long enough to produce a single loop,when cut from the spool and laid unrestrained on a ?at surface,will

(a)Form a circle not less than 4in.[100mm]nor more than 9in.[230mm]in diameter

0.030in.[0.8mm]and smaller sizes;or not less than15in. [380mm]for0.035in.[0.9mm]and larger sizes

(b)Rise above the?at surface no more than1in. [25mm]at any location

Certain bulk packages may contain wire that has been elastically twisted or otherwise treated to provide straight wire feed.Wire from these packages will not form a circle when cut.Traditional cast and helix measurements may have no relevance.Wire thus treated shall conform only

to the winding requirements of19.1and19.2.Any method

648of wire form inspection shall be as agreed between pur-chaser and supplier.

20.Filler Metal Identi?cation

20.1The product information and the precautionary information required in Section22for marking each pack-age shall also appear on each coil,spool,and drum.

20.2Coils without support shall have a tag containing this information securely attached to the?ller metal at the inside end of the coil.

20.3Coils with support shall have the information securely af?xed in a prominent location on the support.

20.4Spools shall have the information securely af?xed in a prominent location on the outside of at least one?ange of the spool.

1.Outside diameter of barrel shall be such as to permit feeding of the?ller metals.

2.Inside diameter of the barrel shall be such that swelling of the barrel or misalignment of the barrel and?anges will not result in the inside

diameter of the barrel being less than the inside diameter of the?anges.

3.Holes are provided on each?ange,but they need not be aligned.No driving holes required for4in.[100mm]spools.

4.Metric dimensions and tolerances conform to ISO544except that"A"speci?es±tolerances on the nominal diameter,rather than a plus

tolerance only,which is shown here as a maximum.
