摘　　要：采用双丝MIG、单丝MIG焊接工艺在相同条件下对616高强钢进行了焊接。分析焊缝内部的质量、焊接接头的组织、焊接接头的强度,对比两种工艺的焊接效率和线能量,研究结果表明:在焊缝内部质量、焊接强度方面,双丝焊优于单丝焊;在焊接效率上,双丝焊是单丝焊的3倍;在单位线能量上,双丝焊比单丝焊降低了32.1%。Under the same condition,616 high strength steel is welded by double wire MIG and single wire MIG welding technology. The inner quality of welding line,the welding structure,the mechanical property,the welding efficiency and the line energy of the two types of welding methods are contrastively studied. The results show that the inner quality of welding line and the welding structure of the double wire MIG are superior to that of the single wire MIG; the welding efficiency of the double wire MIG is two times that of the single wire MIG;the line energy of the double wire MIG decreases 32.1% than that of the single wire MIG.
