The time between weld completion and NDT can vary depending on the steel and standards used. A good example is AWS D1.1. In Section 6 there is an introductory paragraph on NDT (6.11). For welds subject to NDT in
More welding power enlarges the weld nugget and leads to a higher weld quality. In these tests, the optimum for Hilumin was reached at 340 Ws and for CuZn37 at 350 Ws. Further increasing the welding energy leads to electrode sticking and significant expulsion of bulk material [2], [5], [6], [9]. Download : Download full-size image; Fig. 6.
