摘要： A device for confirming an open state of a welding gun having a reciprocating mechanism or moving a movable electrode into and out of contact with a workpiece has a pin feeler mounted on an end of a cylinder of the reciprocating mechanism and movable into and out of contact with a piston movably disposed in the cylinder. The device also has a helical compression spring for resiliently biasing the pin feeler, a housing accommodating the biasing means, and a proximity switch fixedly mounted in the housing. When the piston moves in a direction to open the welding gun, the piston presses and moves the pin feeler until an end of the pin feeler is detected by the proximity switch to confirm the open state of the welding gun. The open state of the welding gun can be detected without being adversely affected by dust and dirt particles, grease, and a mist in the cylinder. The device can be assembled highly efficiently.

摘要： Electrodes are embedded respectively in a first die and a second die. A metal workpiece is placed in a cavity defined between the first die and the second die which mate with each other. Then, a molten metal is poured through a passage into the cavity. The molten metal is solidified into a casting, forming a contact region of the metal workpiece and the casting. Thereafter, an electric current is supplied from a power supply between the electrodes across the contact region. The supplied electric current breaks an oxide film that is present on the surface of the metal workpiece, and joins the metal workpiece and the casting in the contact region.

摘要： When a workpiece which is made up by laminating a plurality of plates of different thicknesses is welded by using a spot welding gun having a pair of electrode tips, the electrode force to the workpiece by one of the electrode tips, which is positioned on the side of a thinner plate, is made larger that the electrode force to the workpiece by the other of the electrode tips. The contact pressure on the side of the thinner plate becomes larger with the result that the contact resistance decreases. Therefore, the nugget on the side of the thinner plate becomes smaller than the nugget on the side of the thicker plate.

摘要： A recess portion with a substantially circular cross-section is provided in the upper end surface of a supporting jig. When a probe of a device for friction stir welding is buried in the upper end surface of a layered portion, material in the vicinity of the buried portion flows plastically. This causes the plastically flowed material to flow into the recess portion, and as a result, the material is stirred in a relatively large region. When the material that flowed into the recess portion is cooled and solidified, a friction stir-welded portion-possessing member having a projection portion is obtained.
