采用单丝埋弧焊在X80管线钢板表面进行堆焊,测量了焊缝的尺寸包括焊缝宽度、余高和熔池长度。固定焊接电压和焊接速度,研究了焊接电流对焊缝尺寸的影响。测量结果表明,焊接电流对焊缝宽度几乎没有影响;随着焊接电流的增大,余高增大,熔池长度先减小后增大。
The single wire submerged arc welding is used to build surfacing on the surface of X80 pipeline steel. The size of the weld is measured including the weld width, residual height and weld pool length. Fixed welding voltage and welding speed, the welding current size of the weld study. The measurement results show that the welding current has almost no effect on the weld width. With the increase of welding current, the residual height increases and the length of the weld pool decreases first and then increases.
