A curved electrode includes an installing portion to be installed in an electrode holder, an offset portion by which the offset amount is obtained, and a tip portion which comes into contact with the material to be welded W, the portions being formed separately and assembled together. A vertical hole and a horizontal hole are formed within the installing portion, an axis hole is formed within the offset portion, and a water supply tube is inserted into a cooling hole which is constructed of the vertical hole, the horizontal hole and the axis hole. C-chamfering or R-chamfering is conducted to a corner where the vertical hole and the horizontal hole intersect. An object of the present invention is to provide a curved electrode which can be manufactured easily at a low cost, and if a part of it is damaged, only that part needs to be replaced at a low cost. The durability of the curved electrode can be improved at the same time.

Curved electrode for welding

The present invention relates to a nut positioning pin disposed on a lower electrode for the projection welding of a nut. The present invention increases cooling and positioning accuracy, prevents entrance of sputtering particles, and increases the detecting accuracy. The present invention comprises an electrode holder () of a double-tube structure having a cooling water passage, a guide ring () for guiding a coupling rod () for vertical movement, an air passage (m) for preventing the entrance of sputtering particles, a coupling block () and a magnetic shield, which comprises a magnetic member for preventing a magnetic detecting element from being affected by an external magnetic field. The present invention accurately guides cooling water and the coupling rod in the electrode holder and prevents sputtering particles from entering the electrode holder, and prevents a detector from being adversely influenced by an external magnetic field for increased detecting accuracy.
