Description

Technical Field

[0001] The utility model relates to a pipeline argon arc welding auxiliary device, in particular to an argon gas pipeline construction protection device, belonging to the technical field of pipeline welding. Background Art

[0002] When performing argon arc welding on small-diameter pipes, workers will put sponges at both ends of the pipes to seal them and supply argon gas into the pipes before welding the pipe joints. However, this construction method is only applicable to small-diameter pipe construction. In the argon arc welding construction of large-diameter pipes, at least two workers are required to cooperate. One worker welds at the interface on the outside of the pipe, and the other worker holds the argon hood inside the pipe and cooperates with the external welder to move and weld. This method is time-consuming and labor-intensive, and holding the argon hood for a long time will cause sore arms for the workers. Utility Model Content
