摘要
对熔化极气体保护焊(MIG/MAG)、钨极氩弧焊(TIG)等焊接工艺及设备进行复合化高效改型,有利于实现低成本、高质量、高熔敷率、高焊接速度的优质高效焊接,对提高制造业焊接工艺制作效率有重要意义。近年来,国内外推出了MIG/MAG、TIG等电弧焊接工艺各类的高效化复合焊接技术与设备。综述双丝MIG/MAG焊接、双MIG/MAG双面焊接、双TIG复合焊接、TIG-MIG复合焊接等双电弧共熔池高效焊接技术的工艺原理及应用。着重介绍了MAG-TIG双电弧热源高效打底焊接新工艺。
The welding technology and equipment of MIG/MAG and TIG,which are widely applied,have been modified with high effi-ciency by composite/hybrid welding.It is beneficial to realize high quality and high efficiency welding with low cost,high quality,high depositing rate and high welding speed,and is of great significance to improve the manufacturing efficiency of welding technology.In recent years,MIG/MAG,TIG and other arc welding technologies and equipment with high efficiency have been introduced at home and abroad.In this paper,the principle and application of high efficiency welding technology of double arc pool,such as double wire MIG/MAG welding,double MIG/MAG double-sided welding,double TIG composite welding and TIG-MIG composite welding are summari-zed.Finally,the new technology of MAG-TIG double arc heat source composite high-efficiency root welding is introduced emphatically.
