摘　　要：采用汉诺威质量分析仪,三种弧焊电源对比,研究了CO2气体保护焊在高速焊接情况下,焊接速度对焊接短路过渡周期和焊缝外形的影响。结果表明,当焊接速度提高时,短路过渡周期增加,但增加幅度不规律,同时,焊缝驼峰起伏加剧。分析表明,焊接速度提高,保护气体周围空气流动速度增大,电弧温度降低,焊丝能量输入减小,短路过渡周期增大,焊缝成形变差。The effects of welding speed on short-circuit transfer and weld formation under high-speed CO2 welding was researched by welding quality analyzer of Harmover with three kinds of welding power. The results show that air flowing speed around shielding gas increased, and then arc temperature reduced, the input energy on wire reduced, short-circuiting transfer cycle increased, result in the welding formation got worse.
