Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings: as shown in the figure, a large-scale pipeline double-sided welding machine includes a frame 1, and the frame is provided with a fixture device 2 for installing a workpiece 9, which is formed by a first power mechanism. The first welding head 3 driven and the second welding head 4 driven by the second power mechanism; the first welding head is used to weld the outer wall of the workpiece; the second welding head is used to extend into the inner wall of the workpiece Weld. The first welding head is used to weld the outer wall of the workpiece, and the second welding head is used to weld the inner wall of the workpiece. Further, the first welding head and the second welding head can be welded in the same direction at the same time, which can better explode the weld. Beautiful and strong, the two halves of the workpiece need to be spot welded to make them roughly connected ...

Abstract

The invention discloses a large pipeline double-face welding machine and a welding method. The problem that the working efficiency is low when large bent pipes are welded at present is mainly solved. The automatic welding machine is characterized in that a clamp device (2) used for installing a workpiece (9), a first welding head (3) driven by a first power mechanism and a second welding head (4) driven by a second power mechanism are arranged on the rack; the first welding head is used for welding the outer wall of the workpiece; and the second welding head is used for stretching into the inner wall of the workpiece for welding. According to the double-face welding machine for the large pipeline, a bent pipe can be conveniently welded, double-face welding is achieved, and a welding seam is more attractive and firmer.

Description

technical field [0001] The invention relates to the field of large-scale pipeline welding, in particular to a large-scale pipeline double-sided welding machine and a welding method. Background technique [0002] In the welding of large pipelines (such as gas and oil pipelines), due to the large workpiece, the operation is not easy. The current conventional working method is that workers need to hold the pipe fittings for welding, and the work efficiency is low. One worker cannot weld many pieces a day. Pipe fittings, and improper operation may cause danger such as smashing. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the background technology, the present invention provides a large-scale pipeline double-sided welding machine, which mainly solves the problem of low work efficiency when welding large-scale elbows at present. [0004] The technical scheme adopted in the present invention is: [0005] A large-scale double-sided welding machine ...
