随着制造业的迅猛发展,焊接结构的生产量逐年增加,这对焊接效率提出了更高的要求。在诸多焊接方法中,双丝串列MIG/MAG焊作为一种高效优质焊接方法,可以大幅度地提高焊接速度和金属熔敷率,从而提高焊接效率[1]。双丝串列MIG/MAG焊既解决了传统单丝焊在高焊速时容易出现的未焊透、咬边、成形差等,又解决了高送丝速度时熔滴过渡的困难。此外,它还具有电流调节范围宽、飞溅少、变形小、焊缝成形好等优
With the rapid development of manufacturing industry, the production of welded structure increases year by year, which puts forward higher requirements on the welding efficiency. Among many welding methods, double-wire tandem MIG / MAG welding is an efficient and high-quality welding method, which can greatly improve the welding speed and metal deposition rate, thereby improving the welding efficiency [1]. Double wire series MIG / MAG welding not only solves the traditional single wire welding at high welding speed prone to incomplete penetration, undercut, forming poor, but also to solve the high wire speed droplet transfer difficulties. In addition, it also has a wide range of current regulation, spatter, small deformation, welding and so good
