Description

Technical Field

[0001] The utility model relates to the technical field of pipe welding devices, in particular to a rapid cooling device for a pipe welding machine. Background Art

[0002] Pipeline welding is the process of joining two pipe parts together, usually using arc welding, TIG, MIG and other methods. Pipeline welding ensures the tightness of the pipe joint to prevent liquid or gas leakage.

[0003] A lot of heat will be generated during the welding process. Most of the pipes are cooled naturally after welding, but the natural cooling is slow.
