According to the development process of long-distance pipeline automatic welding products in the world, at present, the all position automatic welding machine for long-distance pipeline is divided into pipeline internal welding machine (hereinafter referred to as internal welding machine) and pipeline external welding machine (hereinafter referred to as external welding machine). The external welding machine is divided into single torch external welding machine and double torch external welding machine according to the number of welding torch, and the internal welding machine is divided according to the pipe diameter and the number of welding torches.

Internal welding machine is an automatic welding equipment with the highest root pass welding efficiency and the best one-time qualified rate of welded joint for long-distance pipeline. One pipe joint dia. 1219mm can be welded by internal welding machine in 90 seconds, and it can travel inside pipe automatically. Before welding, the ends of two pipelines are clamped and fixed and butt welded by internal welding machine. It can also be used on vessel in offshore project . The internal welding machine is a highly integrated product with electric, pneumatic and mechanical device. It is composed of host, reach rod, control panel etc. The reach rod is used for remote operation.

    The single torch and double torch external welding machine are mainly composed of welding head, wire feeding system, portable panel, welding power source, cable, track etc. All position welding is realized by welding head walking on the track. Single torch can realize the welding of pipe joint with different bevel design, while normally double torch only weld pipe joint with narrow groove design. It is a kind of high-efficiency welding equipment for pipe external welding. Of course, the current single torch and double torch external welding machine also need welders to participate in the welding process to ensure the quality of the weld.

automatic welding

    With the progress of artificial intelligence technology, all position automatic welding machine for long-distance pipeline will become more automatic and intelligent. At that time, we believe that in the near future, the new generation of pipeline welding machine will be installed in the field, and the welding operation can be controlled in office thousands miles far away from the field.
