铝合金MIG焊快速成形问题及计算机分析

MIG welding rapid prototyping of Aluminum alloy and its computer analysis

基于熔化极惰性气体保护焊快速成形技术,引入激光热源,提出激光-TIG复合热源快速成形技术,并采用该技术制作铝合金墙体零件。结果表明:相比常规M IG焊,激光-MIG复合焊过程中电弧在激光的作用下,其作用范围减小,作用精度提高,稳定性增强,提高了零件表面质量和精度。

Based on the metal inert gas welding rapid prototyping technology,the laser heat source is introduced and laser-TIG hybrid welding rapid prototyping technology is proposed in this paper,and an aluminum wall parts are formed by this technology. The results show that：compared to conventional MIG welding,the laser reduces the scope of the arc,improves the precision and stability in laser-MIG hybrid welding process,and thereby improves the surface quality and precision of parts.
