摘要
介绍了一种新型交流ＭＡＧ焊接电弧稳定性及其控制的研究成果。提出了一种崭新的双凹电流波形，解决了ＭＡＧ焊交流电弧稳定这个一直很难解决的问题。对交流脉冲ＭＡＧ焊接电弧稳定性进行了较为系统的研究表明，脉冲参数是影响电弧稳定和实现合理熔滴过渡的最主要因素，保护气体成分和流量、稳弧剂也是重要的影响因素。经过精心配置焊接参数的交流脉冲ＭＡＧ焊接法能实现电弧稳定并具有较合理的熔滴过渡形式，是一种具有重要应用前景的焊接方法。
A new A.C. pulsed MAG welding process was introduced in this paper.A brand-new welding current waveform for stabilizing the A.C. MAG welding arc has been put forward,and the welding test has been performed with satisfactorg results.A set of reasonable pulse parameters was proposed on the welding testing results.Other facttors influencing the arc stability have also been studied.
