DIN EN ISO 15792-3:2011-08 EN ISO 15792-3:2011 (E) 4 1 Scope This part of ISO 15792 specifies the preparation and assessment of fillet weld test pieces for conformity assessment of

24、positional usability and root penetration requirements for consumables classification standards for welding non-alloy and fine grain steels, low alloy steels, stainless steels, and nickel base alloys. This part of ISO 15792 does not specify acceptance requirements. 2 Normative references The followi

26、eneral requirements Samples of welding consumables (electrodes or wires) to be tested shall be representative of the manufacturers products being classified. Test pieces shall be prepared and tested as specified in Clauses 5 and 6, as well as in the classification standard. The test results shall fu

27、lfil the requirements of the classification standard. 4 Test plate material The plate material shall be selected from the range of materials and material thicknesses specified in the classification standard. The surfaces to be welded shall be free of scale, rust, and other contaminants. 5 Preparatio

28、n of the test piece 5.1 Before assembly, the web piece of the assembly shall have one edge of the web flat and square throughout its length so that, when the web is set on the flange, which shall be straight and smooth, there will be intimate contact along the entire length of the joint. The web and

29、 flange shall be assembled as shown in Figure 1. Both ends of the joint shall be secured by tack welds to maintain intimate contact along the length of the joint and to maintain the 90 angle between the web and flange. The web and flange dimensions shall be in accordance with those given in the elec

Figure 1 Preparation of fillet weld test piece 5.2 The position of welding and conditions of welding shall be as prescribed in the relevan

32、t standard for the classification and size of consumable under test, and as defined in ISO 6947. A single pass fillet weld shall be deposited on one side of the joint for approximately the full length of the test piece. The minimum temperature of the assembly shall be 5 C. For covered electrodes, at

33、 least one electrode (and as many more as the weld permits) shall be continuously consumed to within the permissible stub length of 50 mm. For electrodes longer than 450 mm, designed specifically for use in gravity welding, the fillet weld may be made either manually or with a device designed specif

34、ically for gravity welding. For wire electrodes, tubular cored electrodes and wires, welding shall be continuous from start to finish of the fillet weld. 5.3 The fillet shall be deposited using welding speeds compatible with the consumable classification and tested to provide the fillet weld size re

35、quired by the electrode classification standard. 5.4 If welding of the second side of the test piece is required by the consumable classification standard, the test piece shall be cooled to room temperature by any convenient means, before starting to weld the second side of the joint. DIN EN ISO 157

36、92-3:2011-08 EN ISO 15792-3:2011 (E) 6 If water is used as the coolant, care shall be taken that all water has been thoroughly removed from the joint before beginning welding on the second side. 6 Examination of the test piece 6.1 Throat thickness and leg length shall be measured at a minimum of thr

37、ee points along the length of the weld using an appropriate gauge to demonstrate conformity with the requirements of the classification standard. For covered electrodes, where two or more electrodes are used, a macrosection, approximately 25 mm wide, shall be removed from a point approximately 25 mm

38、 back from the crater end of the deposit made with the first electrode. For continuous consumables and covered electrodes where only one electrode is used, a macrosection, approximately 25 mm wide, shall be removed from approximately the midpoint of the weld length. 6.2 One surface of the macrosecti

39、on shall be polished, etched, and scribed as shown in Figure 2. The throat, convexity or concavity, and leg lengths of the fillet weld shall be determined to the nearest 0,5 mm by actual 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 both fillet welds shall be measured on the same macrosection. a) Convex fillet weld b) Concave fillet Size of fillet weld leg length of largest inscribed isosceles right angle. Fillet weld size, convexity and leg lengths shall be determined by actual

41、measurement (to nearest 0,5 mm) on a section laid out with scribe lines as shown. aLeg length = fillet weld size. eTheoretical throat. bConvexity or concavity. fFillet weld size. cScribe lines. gLeg length fillet weld size. dDifference in leg length. hLeg of fillet.

43、n in Figure 3. If, during bending, the weld pulls out of the test plate, it shall be considered 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 the following procedures may be used: a) reinfor
