【Abstract】 A new technology of double-sided arc welding of alternating pulse current was introduced in this paper. After some experiments on aluminium alloy, it is found that this technology could increase the one-pass depth, reduce the heat input and remarkably reduce the workpiece distortion, etc. So, this technology has great prospect of application. Some skills to avoid the generation of double arc was introduced too.更多还原
