Abstract
Provided is a method of manufacturing a joined member that is manufactured by applying resistance welding to a workpiece. The workpiece is provided with plating layers on sides to be in contact with electrodes. In a state in which a first electrode is in contact with a first area in a first plate material that is curved along a contour of a leading end of the first electrode and in which a second electrode is in contact with a second area in a second plate material that is curved along a contour of a leading end of the second electrode, energization between the first electrode and the second electrode is started to form a nugget.
Claims7
A method of manufacturing a joined member, the joined member being manufactured by holding a workpiece comprising stacked plate materials between a first electrode and a second electrode, and applying resistance welding to the workpiece,
- a first plate material in the workpiece that makes contact with the first electrode being provided with a plating layer on a side to be in contact with the first electrode, and a second plate material in the workpiece that makes contact with the second electrode being provided with a plating layer on a side to be in contact with the second electrode,
- the method comprising, in a state in which the first electrode is in contact with a first area in the first plate material, the first area being curved along a contour of a leading end of the first electrode, and in which the second electrode is in contact with a second area in the second plate material, the second area being curved along a contour of a leading end of the second electrode, starting energization between the first electrode and the second electrode to form a nugget.
