A SUBMERGED ARC WELDING PROCESS ; A WELDING WIRE FOR SUBMERGED ARC WELDING WITH SOLID LUBRICANT ON THE SURFACE OF THE WIRE,AND SUBMERGED ARC WELDING DEVICE WITH SUCH WIRE

摘要

The copper cladding normally applied to the surfaces of a submerged arc welding wire for preventing weld gun contact tip abrasive wear is replaced with a solid lubricant. This eliminates copper contamination of the weld from the copper cladding while preserving the useful life of the contact tip.
