Description

technical field

[0001] The invention relates to the technical field of pipe welding, in particular to a welding and forming machine for connecting flanges of elbows. Background technique

[0002] Pipes are parts used to transport gas, liquid or fluid with solid particles. Pipes are divided into straight pipes and curved pipes. The curved pipes are mainly used for the connection at the corners of the pipes. Generally, in order to facilitate the installation of the pipes, there will be Welded flanges at both ends such as Figure 9 shown, and it is convenient for the later disassembly and maintenance of the pipeline.

[0003] However, there are currently the following problems in welding elbows and flanges: 1. In order to save costs, some small enterprises usually weld elbows and flanges manually. The pipe and the flange are fixed, and the existing fixture cannot adjust the angle between the elbow and the flange according to the welding requirements, which is prone to welding ...
