ASTM A488/A488M-17 pdf free download.Standard Practice for Steel Castings, Welding, Qualifications of Procedures and Personnel.
1.1 This practice covers the qualification of procedures. welders, and operators for the fabrication and repair of steel castings by electric arc welding.
1.1.1 Qualifications of a procedure and either or both the operator or welder under Section IX of the ASME Boiler and Pressure Vessel Code shall automatically qualify the procedure and either or both the operator or welder under this practice. P-number designations in the ASME grouping of base metals for qualification may be different than the category numbers listed in Table 1. Refer to Appendix XI for a comparison of ASTM category numbers with the corresponding ASME P-Number designations.
1.2 Each manufacturer or contractor is responsible for the welding done by his organization and shall conduct the tests required to qualify his welding procedures. welders, and operators.
1 .3 Each manufacturer or contractor shall maintain a record of welding procedure qualification tests (Fig. I), welder or operator performance qualification tests (Fig. 2), and welding procedure specification (Fig. 3), which shall be made available to the purchaser’s representative on request.
1.4 The values stated in either SI units or inch-pound units are to he regarded separately as standard. The values stated in each system may not he exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.4.1 SI Units—Within the text, the SI units are shown in brackets.
5.2 The dimensions of the test plate shall be such as to provide the required number of test specimens.
5.3 The test joint shall be welded using the type of welding groove proposed in the welding procedure. The dimensions of the welding groove are not essential variables of the welding procedure.
5.4 The thickness of the test plate shall depend on the range of thickness to be qualified as shown in Tables 2 and 3.
5.5 The joint preparation shown in Fig. 5 shall qualify the supplier for all welding on steel castings.
5.6 Where pipe or a cylindrical casting is used for qualification. it is recommended that a minimum nominal diameter of 5 in. [125 mm] and a minimum thickness of 3/8 in. [1 0 mm] be used.ASTM A488/A488M pdf download.
