摘要

通过端接接头的激光-MAG复合焊接实验, 研究了焊接方式、光丝间距、能量输入等对熔滴过渡行为及气孔缺陷特征的影响规律。研究结果表明:激光-MAG复合焊接比单激光焊更适用于端接接头的焊接, 可以改善焊缝的成形, 抑制气孔缺陷; 激光引导方式优于电弧引导方式, 得到的焊缝内的气孔缺陷较少; 适当增加光丝间距有利于焊接过程的稳定性; 电弧能量输入主要影响焊缝形态, 而激光能量增加则会阻碍熔滴过渡, 并使焊缝底部产生气孔缺陷。

Abstract

The effects of welding mode, laser-wire distance, energy input on droplet transfer behavior and the weld porosity defects are studied by laser-MAG hybrid welding process of edge joint. The research results show that laser-MAG hybrid welding is more suitable for the edge joint because of the improvement of weld formation and inhabitation of porosity. Laser leading mode is better than arc leading mode for the less weld porosity. A large distance of laser-wire is beneficial for the stability of welding process. The arc energy input mainly affects the weld formation, while the increase of laser power prevents droplet transfer and increases porosity defects at the bottom of the weld.
