Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to galvanized round pipe welding equipment. Background Art

[0002] Galvanized round pipe is a pipe with a circular cross-section and a layer of zinc on its surface. This pipe is mainly made of low-carbon steel or alloy steel. Its circular structure enables it to evenly disperse force when under pressure. It is widely used in many fields such as construction and machinery manufacturing. When using galvanized round pipes, it is often necessary to weld two galvanized round pipes together.

[0003] At present, when the ends of galvanized steel pipes are positioned and fixed for welding, the equipment or fixtures are usually designed according to the vertical docking method of the steel pipe ends. However, when two steel pipes are welded at a certain tilt angle, the conventional positioning and clamping structure cannot adapt well to this non-vertical docking situation. At this time, the general method of manual support and pressing is to operate, but this method has many disadvantages. On the one hand, workers are very likely to be burned by welding sparks during the welding process and face threats to their personal safety; on the other hand, since it is difficult for manual support to always maintain absolute stability, it is very easy to cause the steel pipe to shift in position during the welding process, resulting in crooked welding of the steel pipe, which will undoubtedly have an adverse effect on the welding quality, and may further affect the overall performance and reliability of subsequent related projects or products. Therefore, how to improve this welding and fixing method to solve the problems faced when welding steel pipes at tilted angles has become one of the key issues that need to be solved urgently. To this end, we propose a galvanized round pipe welding equipment. Summary of the invention
