Welding Head

A welding head for a welding device for welding a component which is not rotationally symmetrical onto a workpiece including a metal sheet, comprising:

• a head base;
• a head attachment connected to the head base by a drive device operable to move the head attachment with respect to the head base, the head attachment including:
• a holding device for temporarily holding the component for welding and adapted for carrying a welding current to the component;
• and
• a mouthpiece arranged to surround the component during a welding operation, the holding device and the mouthpiece movable in relation to each other along a welding axis;
• an interface device;
• a connecting device, the holding device mechanically connected by the connecting device to the interface device, the connecting device operating to supply the welding current, the connecting device subdivided into a first connection piece and a second connection piece electrically insulated from the first connection piece.
