Formation of resistance of welded seams against forming of hot cracks when welding is performed with an increased speed

ABSTRACT The results of experimental studies of some features of non-consumable electrode welding in argon steel 12X18H10T with increased speed are presented. The possibility of improving the quality of formation and resistance of seams against the formation of hot cracks by exposing the arc and metal of the weld pool by controlling the magnetic field of the current flowing through the contact conductor located above the tail section of the weld pool, perpendicular to the electrode is shown.
