PIN HOLDER FOR USE IN BUTT WELDING OF PINS AND WELDED COUNTER-COMPONENT FOR BUTT WELDING OF PINS

摘要

The bolt holder (7) has a fixing section (9) at its back end for joining it to a bolt welding head. It has a substantially vertical middle section (11) which is joined to the fixing section, and is radially displaced relative to the fixing section. At its front end the bolt holder has a holding section for the component (bolt) to be welded. The axis of this component is substantially coincident with the axis of the pin (9a), while the head section of the component is accommodated in the space partially bounded by the bolt holder sections (9, 11, 13).
