  • Method and an apparatus for automatic electric welding
    Patent number: 4088866
    Abstract: When carrying out electric fusion welding with at least two current-carrying electrodes, these electrodes are held in a joint holder in non-parallel positions so that they meet in a point of intersection in which melting of the electrode material takes place. Hereby the risk of burn-through is minimized and an additional degree of freedom which can be used for controlling purposes is obtained.
