Pipeline automatic welding machine safe operation and precautions
1 Selection and introduction of all-position automatic TIG welding process In the pipeline manufacturing and installation process in the petrochemical, electric power and other industrial sectors, in many cases, the pipeline cannot be rotated. For example, manual TIG welding is used. The butt joint weld must be fully welded in the flat welding, vertical welding and overhead welding. Single-sided penetration welding, and to ensure that the root of the ring is fully penetrated, and the back is well formed and uniform. If pulsed automatic TIG welding is used and the welding process parameters are used to control the program, a fully penetrated, uniformly formed girth weld can be obtained. The application of pulse technology in TIG welding has made the TIG welding process more complete. It has become an efficient, high-quality, economical and energy-saving advanced welding process that can weld metal materials with high heat sensitivity that were previously considered difficult to weld.
