It is a process that is used on a variety of different objects, mainly heavy objects like ships, pressure vessels, the offshore industry, bridges, tanks and heavy duty pipessp.info How does the submerged arc welding process work?In the submerged arc welding process the flux-covered electrode is replaced by the granular flux and a bare electrode. An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux. This flux keeps the atmospheric contamination away. The process may be automatic or semi-automatic.See all results for this question
