ABSTRACT:
A welding head for narrow gap welding is provided with a flat contact nozzle which is pivotable laterally with respect to the longitudinal extent of the gap by being journaled in a similarly flat nozzle holder by means of a shaft which is substantially parallel to the longitudinal extent of the gap and is fully insertable in the gap together with the contact nozzle and at least that part of the nozzle holder which carries the shaft. A drive shaft disposed in the nozzle holder at right angles to the shaft cooperates with the contact nozzle by means of a joint for converting a rotary movement generated by a pendulum device into a corresponding pivotal movement of the contact nozzle about its shaft.
