Estimating the term…
A method and apparatus for resistive welding using an electrode holder having an elongated cylinder. The cylinder has a closed end and an open end. The cylinder contains a moveable piston. The piston includes a compression surface and an end adapted to retain a welding electrode. A compressible biasing member is positioned within the cylinder and is compressed between the closed end and the compression surface. An electrode is attached to the holder. The holder is preferably used as a lower electrode holder opposite a moveable upper cylinder. A work piece is placed between the upper cylinder and lower holder. The upper cylinder is extended and applies a force to the holder through the electrodes and work piece. The force causes the biasing member to compress within the lower elongated cylinder and apply a counter force against the lower surface electrode.
A resistance welder comprising:
A method of resistive welding utilizing a moveable cylinder having a first resistive welding electrode, and a second cylinder having a second electrode opposing the moveable cylinder, said second cylinder having a piston and a compressible biasing member, the method comprising:
