Description
Technical Field
The utility model relates to the technical field of welding equipment, in particular to a semiautomatic welding auxiliary device for eccentric pipes.
Background
At present, in the prefabrication process of the process pipeline of the offshore oil platform, eccentric large and small head pipe fittings are used for connection according to design requirements, so that the use requirement of medium in the pipe is met. After the pipeline assembly is completed, when the semi-automatic welding machine is used for welding, irregular changes can occur in the fixed-point track of the welding line when the welding line at one end of the eccentric large-small-head pipe fitting rotates by 360 degrees, and the fixed distance between the welding gun and the welding line cannot be kept, so that the semi-automatic welding machine cannot be used for welding. Semi-automatic welders are limited to welding of coaxial pipeline welds. When a short pipe with a flange is welded, the axial distance between a welding line and a chuck is too short, and the yaw stroke of a welding gun is insufficient, so that the welding cannot be performed by using a semi-automatic welding machine.
