Modern welding grounding clamps not only have good conductivity and stability, but also improve the durability and environmental protection of the product through advanced material technology and design.

[0003] During the electric welding process, a grounding clamp is needed to connect the workpiece to be welded with the grounding wire of the welding equipment. When in use, the welding rod of the electric welding equipment forms a loop during welding. The existing grounding clamp is adapted to welding pieces of different shapes and maintains sufficient clamping force. The clamping ends of the two clamp arms of the grounding clamp are provided with arc-shaped clamping pieces. The two arc-shaped clamping pieces are mostly made of copper sheets with good conductive properties. Both arc-shaped clamping pieces are conductive.
