Arc welding method - uses magnetic field to position pilot arc or ionised stretch

摘要

In arc welding of metal workpieces, where initially weld points are formed by a pilot arc or ionised stretch, the pilot arc or ionised stretch are positioned as required by the magnetic field generated by the arc. USE/ADVANTAGE - The method is used for applications such as welding bolts to a metal plate. The welding arc is accurately position by the magnetic field to give arc welding without protective gas
