补充资料：高频焊
以高频电流加热工件，然后施加压力形成接头的焊接方法（见图）。利用高频电流集中沿导体表面和沿感抗最小的通路流过的原理，使电流集中加热工件的待焊表面，在达到热塑性状态或局部熔化状态时，对工件加压挤出熔化金属和金属氧化物，便形成焊接接头。高频焊常用频率范围为 60～500千赫。高频焊分高频电阻焊和高频感应焊两种。①高频电阻焊：用滚轮或接触子作为电极将高频电流导入工件，适用于管子的连续纵缝对焊和螺旋搭接缝焊、锅炉鳍片管和换热器螺旋翅片的焊接,可焊管子外径为1200毫米,壁厚为16毫米，工字钢的腹极厚度可焊9.5毫米,生产率很高。②高频感应焊：用感应线圈加热工件,可焊接外径为9毫米的小直径管和壁厚为 1毫米的薄壁管。常用于中小直径钢管和黄铜管的纵缝焊接，也可用于环缝焊接，但功率损耗比高频电阻焊大。影响高频焊接质量的主要参数是高频电源的频率、功率、工件成形角度、挤压力、电极（或感应圈）与挤压辊之间的距离和焊接速度。主要设备有高频电源、工件成形设备和挤压机械装置。高频焊质量稳定，生产率高，成本较低。适用于高效率自动生产线，是生产有缝管的先进方法。
