一般熔化极气体保护焊熔敷速度高,但有飞溅问题;一般钨极气体保护焊无飞溅,但存在焊缝气孔问题。软等离子焊兼备了这两种焊接方法的优点。据国外报导,二氧化碳软等离子焊机的优点是:飞溅少,熔敷速度高,焊缝成形好和焊接烟雾少。二氧化碳软等离子焊适用于低碳钢。用氩气代替二氧化碳作为保护气,可焊铝、铜及其合金。软等离子焊适用于薄板和厚板。 General melting gas shielded welding welding deposition speed, but there is a splash problem; General TIG welding without spatter, but there are weld stomatal problems. Soft plasma welding combines the advantages of both welding methods. According to foreign reports, carbon dioxide soft plasma welding machine has the advantages of: less spatter, deposition rate, weld formation and welding smoke less. Soft carbon plasma welding for mild steel. With argon instead of carbon dioxide as a protective gas, welding aluminum, copper and their alloys. Soft plasma welding for sheets and slabs.
