1.前言热丝焊接方法是一种除电弧外,另外添加一根通电焊丝,利用电阻热熔化焊丝,提高金属熔敷率的方法。热丝应要与TIG电弧或等离子弧等非熔化极电弧配合使用。表1为热丝焊接方法的优点。熔化极电弧(例如MAG焊)中添加热丝的方法,到目前为止几乎还没有人进行过尝试,但从我们的实 1. Introduction Hot wire welding method is a addition to the arc, the addition of a power wire, the use of resistance hot melt wire, metal deposition rate increase method. Hot wire should be used in conjunction with non-melting arcs such as TIG arcs or plasma arcs. Table 1 shows the advantages of the hot wire welding method. The method of adding hot wire to a melting arc (for example, MAG welding) has so far hardly been tried, but from our experience
