ABSTRACT:
A resistance welding electrode is formed of a hollow shank carrying current and cooling fluid and an electrode head connected to the shank by a flexible housing of insulated material. The housing forms a chamber to contain the cooling fluid supplied through the shank. The flexibility of the housing allows the head to rock relative to the shank and also to move axially away from the shank under the influence of the pressure of the cooling fluid. When welding pressure is applied through the electrode to a workpiece, the shank is forced against the head to provide firm electrical engagement between those elements.
