Description

technical field [0001] The invention belongs to a welding auxiliary device and is applied in the field of welding automation, in particular to a magnetic control arc rotation sensor used for welding seam tracking. Background technique [0002] In recent years, with the rapid development of material science and engineering technology, various new welding processes have emerged continuously. The introduction of magnetic field control in the arc welding process is an advanced welding technology currently under development. [0003] Arc is a continuous gas discharge phenomenon, which is composed of a large number of charged particles. Therefore, by introducing a magnetic field during the welding process, the welding arc can be affected by the Lorentz force and follow the magnetic field to make related movements. At present, there are mainly three types of external magnetic field control arc methods: one is to apply a transverse magnetic field, and the magnetic force lines of the...
