Description

Technical Field

[0001] The utility model relates to the field of thermal pipeline processing, in particular to a thermal pipeline laser welding device. Background Art

[0002] The thermal pipeline laser welding device is a device used for efficient and precise welding of thermal pipelines. The device is usually composed of a laser welding machine, a welding head, a control system, auxiliary equipment, etc. The laser welding machine is the core component.
