AUTO ELECTRICITY CONTACT APPARATUS FOR WELDING PIPE USING TURNNING ROLLER

摘要

PURPOSE: An automatic grounding device for pipe welding using a turning roller is provided to minimize the moving distance of a worker during welding by removing the need for connection and separation of a grounding line. CONSTITUTION: An automatic grounding device for pipe welding using a turning roller comprises a support frame part(110) and a rotary grounding part(130). The support frame part includes a support bracket(111). The rotary grounding part includes a grounding plate(134) which contacts the bottom of a pipe after being connected to a grounding line, implements grounding on the pipe, and provides an upward moving force to force the grounding plate to contact the pipe continuously.
