The aluminum alloy is a wide used materials,especially in industrial products.But in laser welding,the many problem exist,such as inducing and stabilizing of keyholes,equivalent strength between base and welding seam,porosity et al.Based on the analysis on these problems,this paper points out the solutions to overcome these problems.The gas flow of gas shield welding should hold the situation of level flow at the pressure of 58.6Pa～78.0Pa,and the technique of wire fillet welding should be employed.
