For low-carbon steel sheets with a thickness of 1-1.5 mm, the maintenance time is 0.1-0.2 seconds, while for welding low-carbon steel with a thickness of 8-10 mm, the full crystallization of the welding nucleus requires around 1.5-2.5 seconds. Therefore, the maintenance time should not be less than this value.
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.
