Title:
WIRE FOR WELDING DISSIMILAR MATERIALS, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/026192
Kind Code:
A1
Abstract:
Provided are a wire for welding dissimilar materials, which makes it possible to reduce a flux filling factor and to suppress generation of filling unevenness, and a method for manufacturing the same. An electrically conductive core wire material and a metal outer skin material comprise aluminum or an aluminum alloy. A coating electrically conductive core wire material provided with a coating layer is formed by applying a flux paste onto the surface of the electrically conductive core wire material, or a coating metal outer skin material provided with a coating layer is formed by applying a flux paste onto an inner surface of the metal outer skin material. Thereafter, a tubular metal outer skin material is formed, and an electrically conductive core wire is arranged inside the tubular metal outer skin material to form a wire for wire drawing. By forming the coating layer over the entire wire in the circumferential direction thereof, even when the flux filling factor is low, flux is disposed over the entire wire in a distributed manner in the length direction and the circumferential direction after solvent in the coating layer has been eliminated.
