Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pipe welding positioning clamps, in particular to an adjustable positioning clamp for pipe welding. BACKGROUND

[0002] There are generally two pipe connection modes, one is port butt welding in the axial direction, and the other is perpendicular to each other and welded into a T-shaped structure. In order to improve stability and safety during pipe welding, a clamp is needed to clamp and position the pipes to be welded. The pipe welding clamp disclosed in the prior art with the technical field number CN221516762U is simple, fast and convenient to operate. In addition, the two clamping assemblies are provided with rollers, so that the two butt-jointed pipes can rotate synchronously, avoiding uneven stress on the rotating pipes and causing cracking or deformation of the previous welded part. However, the clamp angle in the above-mentioned related technology still has the following defects: the clamp angle in the comparative document is only suitable for port butt welding in the axial direction. When T-shaped pipes are welded, it is difficult to position and clamp the two pipes at a perpendicular angle. Therefore, we propose an adjustable positioning clamp for pipe welding.
