Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a steel structure welding clamp. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel frames and other components made of steel and steel plates. When welding steel structures, two steel structures need to be butt-jointed and then welded at the butt joint, especially the welding of steel pipes.

[0003] However, the clamping distance of the welding fixture in the prior art is not easy to flexibly adjust. After fixing a shorter steel pipe, the butted ends of the two steel pipes may not be in contact, and the fixed steel pipe cannot be rotated, which reduces the operability of welding.
