After the test welding of the pipe used in the West-East Gas Pipeline Project, the non-destructive testing of the weld, the mechanical properties and the mechanical test, satisfactory results have been obtained, which proves that the automatic welding has wide application prospects in pipeline construction.
Only the welding speed cannot be stored. They are mirror images of each other and can be welded simultaneously on both sides of the track on the same rail. The nose is connected to the trolley via a pivot and locking structure.The West-East Gas Pipeline Project is a national key project, and it is also an unprecedented large-diameter lsaw steel pipe and high-pressure long-distance natural gas pipeline project in China. The power junction box has two operating voltages, one is 115V and the other is 220V. It includes a gas solenoid valve and a power contact relay. modify the welding parameters in real time..) feeding welding current and shielding gas to the welding torch.
All automatic control functions of the M-300 welder are performed by the control box, which includes various operations, fault diagnosis and release, servo and interconnection control circuits required to control welder travel, swing, wire feed, shielding gas and current. Before welding, the required stored parameters can be directly used up through the menu; in the welding process, according to the weld bead, torch position, molten pool and other factors, through the increase and decrease buttons on the trolley control box The longitudinal and lateral adjustment devices, welding speed knobs, etc.) Provide shielding gas for the arc and the molten pool.
Characteristics of high frequency straight seam welded pipe automatic welding equipment unit:The power junction box provides 28V DC to all working circuits of the M-300 welder. The equipment attached to the handpiece includes a wire feed butt fusion welding machine mechanism, a torch, a gas feed system, a forward sensing head, and vertical and horizontal adjustment devices. In order to ensure the welding quality, reduce the labor intensity of the welder and increase the welding speed, all-position automatic welding should be widely used in the project.The welding trolley is 559mm long, 584mm wide, 381mm high and weighs 20kg. The control box on the trolley can store four sets of welding parameters.
