Thickness of the molten metal interlayer under the arc in submerged-arc surfacing

Priazovsky State Technical University, Mariupol, UkraineAbstract
Method for estimation of thickness of the molten metal interlayer during arc surfacing is suggested. Processes of melting (fusion) of refractory inserts of tungsten and tantalum by the welding arc, as well as their dissolution under the effect of the molten pool metal are considered. It is shown that removal of the molten pool metal during surfacing allows improvement of reliability of the data on thickness of the molten metal interlayer under the arc.
Keywords: arc surfacing, welding arc, molten pool metal, latent component of the arc length, thickness of the molten metal interlayer under the arc
