Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a multi-diameter pipeline continuous welding device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. No matter where it is, welding may be dangerous to the operator, so appropriate protective measures must be taken when welding. The possible harm caused by welding to the human body includes burns, electric shock, visual impairment, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] At present, when pipelines are in use, they usually need to be welded to reach the required length. During welding, in order to ensure the stability of the welding process, the pipelines are usually fixed by clamping. However, traditional clamps are usually selected according to the specific size of the pipeline to achieve the best clamping effect. This results in the need to replace the clamps accordingly when welding and clamping pipelines of different diameters, which is very inconvenient and not conducive to improving the welding efficiency of the pipeline. In view of this, we propose a multi-diameter pipeline continuous welding device. Utility Model Content
