Abstract
Priazovsky State Technical University, Mariupol, Ukraine It is shown that in surfacing in constant longitudinal magnetic field (LMF) of 50 Hz frequency depth and area of the base metal penetration reduce if longitudinal component of induction exceeds 50--60 mT level. In case of wire surfacing, rarefaction forms in LMF on the arc axis. Constant and variable magnetic field of 50 Hz frequency exerts braking action on velocity of molten metal flows in the pool, and this is one of main factors that cause reduction of depth of the base metal penetration in submerged arc surfacing with wire.
Keywords: arc surfacing, low-alloy steel, longitudinal magnetic field, induction, weld pool, arc pressure, penetration
