Priazovsky State Technical University, Mariupol, UkraineAbstract
Equations have been derived for calculation of the electromagnetic field induction in welding of plates and pipes. Calculation and experimental procedures have been used to establish the influence of the part shape on the electromagnetic field of welding current, and a method has been developed to prevent magnetic blow in pipe welding.
Keywords: arc welding, pipe, plate, electromagnetic field, induction, electromagnetic force, electromagnetic pressure, mag¬netic blow, two-sided current supply
