摘　　要：针对采用大规模集成电路LSI芯片的新型逆变气体保护焊机及其输出电流波形控制技术进行讨论。根据选用的保护气体种类,优化直流焊接模式的电流输出,采用"改进型冷桥过渡CBT-EX"的熔滴过渡控制方式对短路过渡进行处理,大大降低了飞溅的发生量。实现了从薄板焊接的低电流领域到厚板焊接的高电流领域的高品质焊接。根据焊接母材材质,优化脉冲波形,获得"一脉一滴"理想的熔滴过渡形式,减少了飞溅量,提高了焊接速度。Discussed the new type inverter gas shielded welding machine using large scale integrated circuit LSI chip and its output current waveform control technology.According to the types of the protective gas,optimized the output current of dc welding mode,using ＂improved cold bridge transfer CBT- EX＂ drop transition control method to deal with short circuit transition,greatly reduced the spatter.Realized high quality welding from the thin plate welding in low current to thick plate welding in high current.According to the parent metal material,optimized the pulse waveform,got the ＂one droplet per pulse＂ ideal form of melting drop transition,to reduce the spatter,improve the welding speed.
