微束等离子焊接是近几年发展起来的一项新型焊接工艺。它多用于电子工业、飞机火箭制造业、原子能工业以及仪表与测量设备中的有色金属薄件和超薄件的焊接。与一般氩弧焊相比,具有能量密度高、穿透力强、电弧稳定性好、焊接速度快、热影响区小等优点。故能焊接氩弧焊所不能焊接的工件,并在一定程度上可代替设备、工艺复什的电子束焊接。成都电焊机研究所研制的 LH—30型微束等离子弧焊机,能焊0.1～1.2毫米厚的不锈钢、可伐合金、低合金钢、镍基合金、蒙乃尔合金、钛及其合金、铜及其合金薄板或细丝。
Micro-beam plasma welding is a new type of welding process developed in recent years. It is mostly used in the electronics industry, aircraft rocket manufacturing, atomic energy industry and instrumentation and measurement equipment in the thin non-ferrous metals and thin pieces of welding. Compared with the general argon arc welding, with high energy density, strong penetration, good arc stability, welding speed, heat-affected zone is small and so on. It can be welded TIG welding can not be welded parts, and to some extent, can replace the equipment, the process of re-even the electron beam welding. LH-30 type micro-beam plasma arc welding machine developed by Chengdu Welding Research Institute can weld 0.1 ~ 1.2mm thick stainless steel, Kovar alloy, low alloy steel, nickel base alloy, Monel alloy, titanium and its alloy, copper And its alloy sheet or filament.
