摘要
研究交流脉冲MIG焊接工艺的主要目的是为了焊接薄板 .交流脉冲MIG使用逆变式交流弧焊电源 ,在电弧变换极性时若不加稳弧措施电弧不能稳定燃烧 .为此 ,在分析了交流脉冲MIG已有的稳弧方案的基础上 ,提出了稳定交流脉冲MIG电弧的控制方案 .在交流脉冲MIG的启弧过程、正常焊接过程、收弧过程中采取了相应控制策略 ,同时结合高压脉冲稳弧控制 ,稳定了交流脉冲MIG电弧 .这种方案的稳弧效果与焊接电流大小无关 。
The main purpose of studying welding technology AC pulsed MIG is used to weld splint.The arc can't burn stably without any arc stabilizaer when it change plority because AC pulsed MIG uses inverter AC power source.Therefore,the control method for stablizing the arc is proposed on base of analyzing others control measure of arc stability.By adopting corresponding control measure in the process of striking arc?normal welding?ending arc and combining high voltage pulsed control circuit,the pulsed MIG arc is stabilized.The measure has extensive adaptability because the effect of arc stability has nothing to do with the current.
