ABSTRACT:
An apparatus and method for depositing an overlay material onto a metal surface. An electroslag strip overlaying process which distributes flux through a trailing flux tube and a forward flux tube eliminates many of the problems associated with electroslag overlaying techniques. The apparatus and method significantly improves the quality of the overlay surface, and permits overlays to be made within the small confines of pipes and pipe fittings having straight or curved surfaces.
