Summary:PROBLEM TO BE SOLVED: To provide a wire for welding dissimilar materials which enables reduction of a flux filling rate and suppression of occurrence of filling unevenness, and a method for manufacturing the wire.SOLUTION: A flux paste is applied onto a surface of a conductive core material thereby forming a coating conductive core material provided with a coating layer, or a flux paste is applied onto an inner surface of a metal covering material thereby forming a coating metal covering material provided with a coating layer. Thereafter, a tabular metal covering material is formed, and a conductive core is located in the tabular metal covering material, thereby forming a wire for drawing. As a result of formation of the coating layer over the circumferential whole of the wire, even if a flux filling rate is low, the flux is so disposed as to be dispersed over the whole of the wire in a lengthwise direction and a circumferential direction after a solvent in the coating layer has disappeared.SELECTED DRAWING: Figure 1 【課題】フラックス充填率を少なくすると同時に充填ムラの発生を抑制することを可能にする異種材料溶接用ワイヤ及びその製造方法を提供する。【解決手段】導電性心線材料の表面にフラックスペーストを塗布してコーティング層を備えたコーティング導電性心線材料を形成するか、金属外皮材料の内表面にフラックスペーストを塗布してコーティング層を備えたコーティング金属外皮材料を形成する。その後に管状の金属外皮材料を形成し、管状の金属外皮材料の内部に導電性心線を配置することにより線引き用ワイヤを形成する。コーティング層がワイヤの周方向全体にわたって形成される結果、フラックス充填率が低い場合でも、コーティング層中の溶媒が無くなった後に、フラックスがワイヤの長さ方向及び周方向全体に分散して配置される。【選択図】図1
