ABSTRACT:
In a submerged arc multiple wire welding system, only one or two of the welding wires used are over or microalloyed wires. The other wires are commercially available unalloyed or low-alloyed solid wires. The process produces a weld metal which has unexpectedly high toughness values, and can be performed more economically. This multiple wire welding system is used in single or multiple-pass welding operations.
