8、ions, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are inclu

9、ded in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can bec

10、ome a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between

11、 the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While the AWS administers theprocess and establishes rules to promote fairness in

12、 the development of consensus, it does not independently test, evalu-ate, or verify the accuracy of any information or the soundness of any judgments contained in its standards.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whetherspecial

32、and as defined in AWS A3.0. A single passfillet weld shall be deposited on one side of the joint for approximately the full length of the test piece. Theminimum temperature of the assembly shall be 15 C 60 F. For covered electrodes, at least one electrode(and as many more as the weld permits) shall

33、be continuously consumed to within the permissible stub lengthof 50 mm 2 in. For electrodes longer than 450 mm 18 in, designed specifically for use in gravity welding, thefillet weld may be made either manually or with a device designed specifically for gravity welding. For wireelectrodes, tubular c

34、ored electrodes and wires, welding shall be continuous from start to finish of the filletweld.5.3 The fillet shall be deposited using travel speeds compatible with the consumable classification and testedto provide the fillet weld size required by the consumable classification standard.5.4 If weldin

35、g of the second side of the test piece is required by the consumable classification standard, thetest piece shall be cooled to room temperature by any convenient means, before starting to weld the secondside of the joint.If water is used as the coolant, care shall be taken that all water has been th

36、oroughly removed from the jointbefore beginning welding on the second side.6 Examination of the test piece6.1 The completed fillet weld test piece shall be examined per the classification standard. Leg length shall bemeasured at a minimum of three locations along the length of the weld using an appr

37、opriate gauge todemonstrate conformity with the requirements of the consumable classification standard. For test plateswelded with covered electrodes, where two or more electrodes are used, a macrosection, approximately 25mm 1 in wide, shall be removed from a point approximately 25 mm 1 in back from

38、 the crater end of thedeposit made with the first electrode. For test plates welded with a continuous consumable or with only onecovered electrode is used, a macrosection, approximately 25 mm 1 in wide, shall be removed fromapproximately the midpoint of the weld length.6.2 One surface of the macrose

39、ction shall be polished, etched, and scribed as shown in Figure 2. Theconvexity or concavity, and leg lengths of the fillet weld shall be determined to the nearest 0.5 mm 1/64 in byactual measurement of the polished and etched macrosection.If fillet welds are required by the consumable classificatio

40、n standard on both sides of the test piece, then bothfillet welds shall be measured on the same macrosection.6.3 For fillet weld test pieces welded from one side only, when required by the consumable classificationstandard, the remaining two joint sections shall be broken longitudinally through the

41、fillet weld by a forceexerted in the direction shown in Figure 3. If, during bending, the weld pulls out of the test plate, it shall beconsidered as a no test, and the test shall be repeated without penalty.6.4 If necessary to facilitate fracture through the throat of the fillet weld, one or more of

42、 the followingprocedures may be used:a) reinforcing welds, as shown in Figure 3 a), may be added to each leg of the weld;b) the position of the web on the flange may be changed as shown in Figure 3 b);c) the face of the weld may be notched as shown in Figure 3 c);d) the test piece may be cooled down
