Welding process of 316L stainless steel pipe
Welding range
The welding parts of stainless steel pipes are generally limited, and they are generally butt joints and lap joints between pipes and pipes, pipes and Fujian. It is also necessary to use non-polar argon arc welding when welding, and argon gas should be passed on the back to protect the full position of the single-side welding.
welder
The welding personnel here is not a random person who can weld 316L stainless steel pipe welding, must be through the classification society qualification recognition rubber test, and to pass the exam after a period of practice, and through the beam slip through the classification society recognition, in order to participate in the welding of this project. Because the welding of this project requires a very professional person to carry out, and this project is very dangerous, there can be no deviation.
