Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a butt welding device for welding round pipes. Background Technology

[0002] In the construction of steel pipes, welding is required to meet certain structural requirements. Patent document CN210172922U discloses a steel pipe welding device for steel pipe furniture production, including a base. A fixing plate is fixedly installed on the top of the base, and a groove is formed on one side of the front of the base. A connecting plate is movably sleeved on one side of the top of the base, and the bottom of the connecting plate extends into the inner cavity of the groove and is fixedly installed with a slider. One side of the slider is fixedly connected to one end of a spring, and the other end of the spring is fixedly connected to the inner wall of the groove. This steel pipe welding device for steel pipe furniture production, through the cooperation of the fixing rod, clamping plate, fixing sleeve, compression spring, and bolts, facilitates better fixing of the steel pipe and allows the welding device to weld steel pipes of various sizes. This avoids the problem of the welding type of the steel pipe welding device being fixed, which greatly reduces its practicality, thus improving the practicality of the steel pipe welding device.

[0003] Although the aforementioned patent can achieve welding and fixing of steel pipes of various sizes, the feeding of steel pipes is cumbersome, requiring workers to pass the steel pipes through the clamps, coolers, and annular sleeves. In addition, the welding nozzles built into the annular sleeves cannot complete the welding at the joints of the steel pipes, resulting in gaps at the weld positions.

[0004] Therefore, we have made improvements to this and proposed a butt welding device for round pipe welding. Utility Model Content
