60、 the changes of solid wire S (welding process 135) to metal core wire M (welding process 136) or vice versa which do not require a new qualification test (see Table 3). However, it is permitted for a welder to be qualified for two or more welding processes by welding a single test piece (multi proce

61、ss joint) or by two or more separate qualification tests. The ranges of qualification for each welding process used and for the multi process joint for butt welds are given in Table 1 (see also Table 4).各资格测试一般只认证一种焊接工艺。焊接工艺的变化需进行新的资格测试。实心线S(焊接工艺135)到金属芯线M(焊接工艺136)的改变除外,反之亦然,不需要新的资格测试(见表3)。但是,允许焊工通过

62、焊接单个测试件(多个焊接点),或通过两个或以上单独的资格测试,获得两个或以上焊接工艺认证。表1中列出了所使用的各焊接工艺的资格围,以与对焊的多个工艺焊接点(也见表4)。Table 1 Thickness range for single and multi process joints for butt welds表1- 对焊的单个和多个工艺焊接接缝厚度围Welding process used for the test piece测试点所使用的焊接工艺Thickness range厚度围Single process joint单个工艺接缝Multi process joint多个工艺接缝Key图例:1 Welding process 1 (nb)1 焊接工艺1(nb)2 Weldi
