摘要：
Laser bonding welding test of the lap joint between steel and Al was conducted to discuss the influence of process parameters on the quality of steel-Al joint and to conduct the mechanical property analysis. The results showed that the positive weld joint of the specimen was uniformed under the conditions of 1450W laser power, 25m/s welding speed, +5mm defocus amount and 20L/min flow rate of Ar as the protective gas, and continuous free from pores and cracks when glue line was added in laser welding. The shear strength and average shear force were 43.15Mpa and 1.13KN, respectively. The mechanical property was slightly improved because of the glue line.
