When we studied in many welded pipe enterprises, we saw that there were some welding gas protection devices or gas pipes in the welding position during the production process of many pipe making machine production lines, so what role did these things play in the pipe making machine production lines? Here is a brief explanation for everyone.

Welding gas protection is still very helpful to the process of the pipe making machine production line. Because the pipe making machine crimps the steel strip into a pipe during the pipe welding process, and then welds it into a whole, welding oxidation will occur during this welding process. Because the welding is exposed to the atmosphere, oxidation is normal. The welded seam of the pipe will show a black welding line, which will affect the appearance of the pipe, at least it is unsightly. The pipe making machine production line with welding gas protection device uses internal and external welding gas protection during the pipe welding process to achieve this active atmosphere where the welding part is relatively free of oxygen, which greatly reduces the possibility of oxidation. The pipe weld will be relatively beautiful. Some are silvery white, and some are light yellow. For some less demanding pipes, the pipes produced by this pipe making machine can be polished without welding seams, which saves costs.
