ABSTRACT:
A welding electrode comprises an elongate body with a cavity or cavities at one end thereof. The geometry of the cavity or cavities can range from a single simple slot arranged to extend along a diameter of the electrode tip and in the axial direction to terminate short of the region where the taper of the electrode tip commences, to complex cavities such as multi slots. Electrodes according to the invention serve to mitigate the problem of their becoming coated with metal vaporized from the surface of the weld pool.
