Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary tooling technology, specifically a lightweight and portable welding auxiliary tooling. Background Technology

[0002] Welding fixtures are flexible clamps used for fixing, clamping, and positioning welding components. They are mainly used for welding various weldable materials, including large, medium, and small materials. Welding auxiliary fixtures are required during workpiece welding. A lightweight and portable welding auxiliary fixture is a specialized tool or clamp used to improve the welding process, ensure weld quality, and increase production efficiency. It is typically used to position, clamp, and fix the weldment, helping operators achieve accurate welding and thus ensuring the quality and consistency of the weld. However, existing lightweight portable welding auxiliary fixtures still have certain shortcomings.

[0003] While traditional lightweight and portable welding auxiliary tooling can be used effectively, it is inflexible in its application when welding workpieces. It cannot fix workpieces of different sizes and shapes for welding, and the fixation is unstable, causing the workpiece to easily shift during welding. Furthermore, it cannot stably weld workpieces that require welding at different angles, thus reducing the efficiency of the equipment and often troubling users. Utility Model Content
