一、问题的提出用间断的脉冲电流代替连续电流进行焊接,使全位置焊接的机械化自动化更容易实现,单面焊双面成形能较容易地解决,而且可以在较宽的范围内控制线能量以适应焊接接头性能的要求.这种工艺是通过特殊的装置提供频率可调、幅值可调、脉冲宽度比可调的脉冲电流进行焊接的,对应间断的脉冲电流,产生间断的喷射过渡,因此可以用低于临界电流的平均电流来进行喷射过渡焊接.这样就既可以保留了喷射过渡的优点,又
First, the question put forward the use of intermittent pulse current instead of continuous current welding, so that all-position welding mechanization automation easier to achieve, single-sided welding double-sided forming can be easier to solve, but also in a wide range of control line energy In order to meet the requirements of the performance of welded joints.This process is through a special device to provide adjustable frequency, adjustable amplitude, pulse width adjustable pulse current welding, the corresponding intermittent pulse current, resulting in intermittent jet transition, So you can use the average current below the critical current for jet transition welding. This will not only retain the advantages of jet transition, and
