Japanese Patent JP2014164964

A

PROBLEM TO BE SOLVED: To provide a method of manufacturing a terminal which allows for butt welding while enhancing laser welding efficiency, without reducing the strength significantly in a weld zone and the vicinity thereof.SOLUTION: A method of manufacturing a terminal 1 having a tube body caulking portion 30 being crimped to a wire includes a step for preparing a base material composed of copper or a copper alloy of a terminal material including a tube development part for forming the tube body caulking portion 30 by being bent, a step for forming a nickel layer containing 10-70% volume fraction of high melting point inorganic particles having a grain size of 10-300 nm on the tube development part, a step for forming a tin layer, as the uppermost layer, on the nickel layer, a step for shaping into a tube body by bending and butting the tube development part, and a step for forming the tube body caulking portion 30 by jointing the butting part by laser welding of near-infrared laser light irradiation, in this order.
