Xionggu developed three types of automatic pipeline welding machine including internal welding machine, single torch type external welding machine, dual torch type external welding machine. Two welding processes have been developed: 1. Root pass by internal welding machine with solid wire+hot pass and fill & capping by dual torch type external welding machine with solid wire. 2. Internal line up clamp+root pass, hot pass, fill & capping by single torch type external welding machine with solid wire.

 

Welding parameters of internal welding machine

Welding speed 0.25-0.3m/min, wire feeding speed 9.0-10.0m/min. In case of 60° internal bevel, it is necessary to apply faster wire feeding speed. Therefore, welding speed is designed at 0.15-1.5m/min, wire feeding speed is designed at 1.5-15m/min.

Dual torch external welding machine is designed for downhill welding. When solid wire is used, wire feeding speed is 7.6m/min-15.2m/min, travel speed is 0.25m/min-1.4m/min. According to this set of welding parameters, travel speed of dual torch welding machine is set to be 0.1-1.5m/min, wire feeding speed is set to be 2.5-16.0m/min.
