适用范围:1.1.1 This standard covers acceptance tests for wire-flux combinations for submerged-arc welding of mild and low alloy high tensile steels for thickness up to and including 35 mm by the two-run or multi-run techniques for use in structural work, general engineering work, pressure vessels and for hull construction. Approval obtained on the 20 mm thickness with the multi-run technique shall be deemed valid up to 35 mm thickness. Where the thickness exceeds 35 mm, additional tests are necessary and are to be mutually agreed upon.1.1.2 Section 2 specifies requirements for acceptance tests for wire-flux combinations for use with the multi-run technique which give on all-weld metal tests, a tensile strength within the range 400-600 N/mm2 (41-61 kgf/ mm2) and the yield stress not less than 300 N/mm2 ( 31 kgf/mm2). The elongation shall not be less than 22 percent.1.1.3 Section 3 specifies requirements for acceptance tests for wire-flux combinations for use with multi-run technique which give on all-weld metal tests, a tensile strength within the range 460-650 N/mm2 ( 47-66 kgf/mm2 ) and the yield stress not less than 350 N/mm2 ( 36 kgf/mm2 ). The elonga-tion shall not be less than 22 percent.1.1.4 Section 4 specifies requirements for acceptance tests for wire-flux combinations for use with the multi-run technique which give on all-weld metal tests, a tensile strength within the range 520-700 N/mm2 ( 53-71 kgf/ mm2) and the yield stress not less than 450 N/mm2 ( 46 kgf/mm2). The elongation shall not be less than 22 percent.1.1.5 Section 5 specifies requirements for acceptance tests for wire-flux combinations for use with the two-run technique which give on longitudi-nal weld tests, a tensile strength within the range 400-600 N/mm2 (41-61 kgf/mm2 ) and the yield stress shall not be less than 300 N/mm2 ( 31 kgf/ mm2). The elongation shall not be less than 22 percent.1.1.6 Section 6 specifies requirements for acceptance tests for wire-flux combinations for use with the two-run technique which give on longitudinal weld tests, a tensile strength within the range 500-650 N/mm2 ( 51-66 kgf/ mm2) and the yield stress shall not be less than 350 N/mm2 ( 36 kgf/mm2). The elongation shall not be less than 22 percent.1.1.7 Section 7 specifies requirements for acceptance tests for wire-flux combinations for use with the two-run technique which give on longitudinal weld tests, a tensile strength within the range 550-700 N/mm2 ( 56-71 kgf/ mm2) and the yield stress shall not be less than 450 N/mm2 (46 kgf/ mm2). The elongation shall not be less than 22 percent.
