脉冲电流熔化极氩弧焊工艺方法(MIGP)在铝合金结构的焊接生产中所能发挥的优点在国内外很多文献资料早有介绍。铝合金的 MIGP 工艺能有效地控制电弧的熔滴过渡形式;相同的电弧功率能获得比较高的电弧热效率;能提高电弧对熔池正压力,从
The advantage of MIGP in the welding production of aluminum alloy structure is introduced in many literatures at home and abroad. Aluminum alloy MIGP process can effectively control the arc of the droplet transition form; the same arc power to obtain higher arc thermal efficiency; arc can improve the positive pressure on the weld pool, from
