【Abstract】 The processing paraments of laser welding of aluminum alloy 2007 with high power Nd:YAG CW laser are studied.Pores and hot cracks are found in the welding seam. The experiments show that laser welding with filler wire Alsi12 cna minimize hot crack due to the smallest amout of heat input into the ease material.更多还原
