Re melt depositwelding process is proposed in this paper. To realize the technology, plasma arc, TIG arc, high frequency induction, gas shield continuous stove and MSW are adopted.
This welding process, with continuous welding wire feeding, fast deposit speed and quality welding pass, is especially suitable for long distance pipeline with large diameter and thick wall.
