Abstract:
1. A welding head comprising: a bracket; and a plurality of blocks coupled to the bracket, each of the plurality of blocks having a contact tip, the contact tips adapted to receive an electrode, wherein at least one of the plurality of blocks is capable of variable positioning relative to the bracket; the plurality of blocks including a fixed block having a second contact tip; the bracket defining a central axis, and the contact tips of the fixed block having fixed positions and orientations relative to the central axis; and the at least one block capable of variable positioning being guided via the coupling to the bracket for both translational and rotational movement and positioned by an electronic processor, such that an orientation of the contact tip of the at least one block capable of variable positioning diverges from the orientation of the contact tips of the fixed block and a spacing between the contact tip of the at least one block capable of variable positioning and a contact tip of the fixed block is comparatively lesser than a spacing between the two contact tips of the fixed block to reduce welding defects.
