Application
Submerged Arc Welding (SAW) of mild and low-alloy steels for structural, pressure vessel, shipbuilding, pipemill, H-beam manufacturing, and general fabrication. Suitable for welding base metals such as: Mild steels (ASTM A36, A283, A285, A516 Gr.55–70). General carbon-manganese steels used in structural shapes, plates, and pipes.
