摘要： An arm main body of a welding gun is formed of an aluminum alloy. An anodic oxide coating is formed on an entire surface of the arm main body. The arm main body is then machined to remove the anodic oxide coating formed on a power feeing terminal portion and an electrode tip connecting portion which are provided in the arm main body. The anodic oxide coating may be subjected to a sealing treatment with a dispersion liquid in which a magnetic material is mixed in dispersion. Alternatively, the arm main body formed of an aluminum alloy may be subjected to an anodic oxide coating treatment with a treatment liquid in which a magnetic material is mixed in dispersion.

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.

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： A resistance welding apparatus mounted on a robot arm includes a transformer having primary and secondary windings. Two gun arms supporting respective welding electrodes in confronting relation to each other are relatively movable toward and away from each other. Conductors extending from the secondary winding are electrically connected to one of the welding electrodes through one of the gun arms, and the transformer is supported on said one gun arm. Rectifiers are used which have terminals engaging said one gun arm and opposite terminals engaging the conductors. The rectifiers and the conductors are securely joined to the one gun arm.
