摘　　要：等离子弧是采用等离子焊炬压缩自由电弧,形成高温、高电离度和高能量密度的电弧,具有焊接质量高、焊接速度快、热量集中等特点。对比分析了等离子弧与TIG焊的差别。同时,分析了我国使用等离子弧焊机与国外使用量的差距,强调我国应大力发展通用型大电流等离子弧焊接设备,谁在大电流通用型等离弧焊机的研制方面走在前面,谁就站在了焊接时代的前沿。Plasma welding torch compresses free arc to form plasma arc ,which is high-temperature,high-ionization and high energy density, and this arc has some characteristics of good welding quality, fast welding speed and concentrated heat.This paper compares and analyses the difference between plasma arc and TIG arc,and the gap of use of plasma arc welder between home and abroad.It stresses that we should vigorously develop the universal high-current plasma arc welding equipment,and the one who is at the ahead of the study on this welder will stand in the frontier of welding age.
