Metal circular pipe welding device

Abstract

The invention relates to the technical field of metal circular pipe welding processing auxiliary devices, in particular to a metal circular pipe welding device which comprises an operation panel, fourgroups of legs, a welding machine, a left fixed plate, a right movable plate, a left lead screw, a limit square column, a left barrier, a right barrier, a circular boss, a support rod, an upper clampplate, a lower clamp plate, an upper rotary arm, a lower rotary arm, two groups of support springs, a left rotary shaft, a right rotary shaft, a right ejecting plate, a left hand wheel, a rear support plate, an upper ejecting plate, two groups of threaded pipes, two groups of threaded rods, a movable block and a mounting plate. A welding gun is arranged at an output end of the welding machine. The metal circular pipe welding device has the advantages that welded metal circular pipes can be fixedly clamped by the metal circular pipe welding device, two groups of metal circular pipes can be prevented from moving in welding procedures, and the use reliability can be improved; butted weld seams of two groups of circular pipes can be continuously circumferentially welded by the metal circularpipe welding device, weld protrusions at welded circumferential locations can be reduced, follow-up polishing treatment working procedures can be reduced, accordingly, labor force and the economic cost can be reduced, and the practicality can be improved.

Description

technical field [0001] The invention relates to the technical field of welding processing attachments for metal round pipes, in particular to a welding device for metal round pipes. Background technique [0002] As we all know, welding is the process of using various fusible alloys (solder) to connect metal parts. The melting point of solder is lower than that of the material to be welded, so that the parts will end the welding through the intermolecular contact on the surface without being melted, the welding part will not move relative to each other, the contact surface will not be oxidized, and the continuous conduction method It can be insisted that welding is the fusion between two metals. The welding device for metal round pipe is an auxiliary device used for butt welding of metal round pipes so as to better connect the metal round pipe materials. It has been widely used in the field of metal round pipe welding and processing; the existing welding device for metal rou...
