Abstract
Laser-pulse GMAW and laser-continuous GMAW welding possessed good application prospect and wide use.The changes of electric parameters and the weld shape size in the process of these two kinds of heat source form and pulse GMAW welding and continuous GMAW welding were systematically researched.The results showed that the electricity parameter was smooth and the welding process was stable that could enhance the transition of droplets and ideal weld dimension with big penetration and low excess weld metal could be obtained in the laser-pulse GMAW welding.The electricity parameter increased in volatility when the welding process was in short circuit of the laser power was 3 000 W.关键词
