三丝埋弧自动焊是一种高效焊接方法,它可以同时产生三个电弧,以大电流、高速度进行焊接作业。初步估计,其生产率比单丝埋弧自动焊提高3～4倍,特别是省去单丝焊的多层反复焊接、底层和中间层打渣(厚板自动焊最难打渣和劳动强度最大部分)、刨焊根等工序,大大减轻了工人劳动强度,减少了焊接材料消耗量和成本。 (一)三丝埋弧自动焊设备三丝埋弧自动焊机由三丝焊机头(配上纵缝焊接升降装置可焊接筒体纵焊缝,配上焊接平台可进行平板对接焊)、焊接电源和控制系
Three-wire submerged arc welding is an efficient welding method, which can produce three arcs simultaneously, with high current, high speed welding operations. Preliminary estimates, the productivity of single-wire submerged arc welding to improve 3 to 4 times, in particular, eliminating the monofilament welding repeated welding multilayer, the bottom and the middle layer of slag (slab automatic welding the most difficult to fight the slag and the most labor-intensive Part), planing root welding and other processes, greatly reducing the labor intensity of workers, reducing the consumption of welding materials and costs. (A) three-wire submerged arc automatic welding equipment Three-wire submerged arc automatic welding machine consists of three wire welding head (with longitudinal seam welding lifting device can be welded longitudinal welding seam, coupled with the welding platform for flat butt welding) Welding power and control system
