Distribution of welding arc pressure
V.V. Chigarev, S.V. Shchetinin
Priazovsky State Technical University, Mariupol, UkraineAbstract
It was established experimentally that the electromagnetic field induction in the fusion zone grows with the welding speed. This results in an increase of the electromagnetic force and magnetic pressure, directed downwards, that influence the formation of undercuts
