Welding equipment and welding method of seamless steel tube

Abstract

The invention discloses welding equipment and a welding method of a seamless steel tube. The welding equipment comprises a supporting seat, wherein positioning plates are fixedly installed on the twosides of the top of the supporting seat, fixed sleeves are fixedly installed in the positioning plates, adjusting rods are in threaded connection with the interiors of the fixed sleeves, clamping blocks are rotationally installed at one end of each of the adjusting rods, the other ends of the adjusting rods extend out of the fixed sleeves, and a fixed plate is fixedly installed on the front side of the middle end of the top of the supporting seat. One end of the steel tube can be clamped and fixed by arranging the adjusting rods and the clamping blocks, the clamping parts on the inner sides ofthe clamping blocks are arranged to be in an arc shape to be exactly matched with the shape of the steel tube, the stability after clamping can be guaranteed, meanwhile, two clamping sleeves are arranged on the side face of the supporting seat, and the front end of the clamped steel tube can be fixed; and the clamping effect is good, it is guaranteed that shaking cannot be generated during welding, the clamping distance can be adjusted according to the size of the steel tube, and the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe welding, in particular to a seamless steel pipe welding equipment and a welding method thereof. Background technique [0002] Seamless steel pipes can be used to manufacture a variety of equipment parts. Welding of the pipe wall is often required during processing, such as the steering housing under the steering wheel in the automobile steering system. The steering housing is one of the core components in the automobile steering system. The seamless steel pipe connection is welded during processing. The traditional welding method is to position and clamp the seamless steel pipe on the drilling machine with a clamp and then use welding equipment to perform welding operations. However, this traditional welding method is due to the steel pipe The clamping is unstable, and the steel pipe will rotate slightly during the welding process, which will not only reduce the welding quality, but also cause ...
