IPC: F16B35/00
Filed: 1999-07-17
Abstract: PROBLEM TO BE SOLVED: To secure a high deposition strength with a broad welded cross section acquired by an expansion of a molt zone toward an energizing passage cavity at an initial energizing stage by forming a projecting part on the face of a flange of a bolt and energizing while pressing the projecting part of the flange on an objective plate member tightly in contact with an electrode having an energizing passage cavity. SOLUTION: A rising-up part 15 is concentrically formed on a circular flange 14 of a bolt 12 and a vertex 16 is formed at the center of the rising-up part 15. A circular energizing cavity 23 is provided at the end face 21 of a fixed electrode 18 on which the plate member 22 of a steel plate part is mounted. An energizing is executed in a state that the flange 14 is tightly in contact with the end face of a movable electrode 17 and the vertex 16 of the projecting part 15 is in a state of pressurized contact with the plate member 22. A contacting part 24 of the vertex 16 and the plate member 22 is molt at an earlier stage of energizing. As the pressurizing proceeds, the molt part acquires a maximum diameter and the whole zone of the upheaving part 15 is welded.  In the final stage, the plate member 22 is clamped between the flat face 28 of the flange and the flat face 21 of the electrode around the energizing cavity 23, and a swelled part is formed toward the inside of the opening of the energizing cavity 23.
