Process for the submerged arc welding of metallic materials in a narrow gap

摘要

The invention relates to a process for the submerged arc welding of metallic materials in a narrow gap with a consumable wire electrode continuously fed through a nozzle. In this process, the nozzle is set with a curved outlet during the welding operation in a rotary pendulum movement, reciprocating from one flank of the weld to the other, with retention times in its end positions close to the flanks.
