WebA butt weld is a common welding joint that combines two pieces or sheets of metal end to end, that are leveled, i.e. on the same axis and/or parallel to one another. The two pieces are typically flat surfaces/circular pipes that … WebSubmerged arc welding is ideally suited to the longitudinal and circumferential butt welds required for the manufacture of line pipe and pressure vessels. Welding is normally carried out in the flat (BS EN ISO 6947 PA) position because of the high fluidity of the weld pool and molten slag and the need to maintain a flux layer. Fillet joints may ...
