3. Continuous welding

Continuous fusion welding is carried out using the following processes:

• coated electrode welding ;

• submerged or flux-cored welding ;

• MIG and MAG welding (MIG: Metal Inert Gas; MAG: Metal Activ Gas ) ;

• TIG/plasma welding (TIG: Tungsten Inert Gas ) ;

• electron beam (EB) welding ;

• laser welding.

These processes produce a continuous weld seam between the edges of two parts that are brought into contact along their entire length, by relative movement of the workpiece and the tool. In most cases, the lighter, easier-to-handle welding tool is moved evenly along the joint. However, when a workpiece has a circular orbital weld or is close to one,...
