Pipeline automatic welding equipment and welding method

Abstract

The present invention relates to the technical field of pipeline processing, in particular to an automatic pipeline welding equipment and welding method, including a base, a mounting rod, a chute and a docking device. The left and right sides of the upper end surface of the base are symmetrically provided with mounting rods. There is a chute on the left side of the upper end, the installation rod on the left is slidingly set in the chute, the installation rod on the right is fixed on the base, and the upper end of the installation rod is connected with a docking device; For square steel pipes, the butt tightness cannot be guaranteed, the welding effect is not good, and it is necessary to continuously move the pipes to make the butt joints, which increases the burden on the staff; the present invention designs a limited clamping method for square steel pipes. And the machine for welding after butt joint ensures that the welding position is always in a tight state during welding, and there is no need to manually move the joint position, which reduces the burden on the staff.

Description

technical field [0001] The invention relates to the technical field of pipeline processing, in particular to an automatic pipeline welding equipment and welding method. Background technique [0002] Pipes are divided into plastic pipes and metal pipes according to their materials. Among them, steel pipes are steel products with a hollow section whose length is much longer than the diameter or circumference. Steel pipes are economical steel products that can be used to transport fluids and powdery solids. In the manufacture of mechanical parts, etc., steel pipes can be classified into round steel pipes, square steel pipes, rectangular steel pipes and special-shaped steel pipes according to the cross-sectional shape. Among them, the square steel pipes need to be welded to meet the length of use. [0003] At present, when welding square steel pipes, there are usually the following defects: 1. The traditional butt welding machine needs to clamp and butt two square steel pipes fi...

Problems solved by technology

[0003] At present, when welding square steel pipes, there are usually the following defects: 1. The traditional butt welding machine needs to clamp and butt two square steel pipes first, and then weld the butt joints. The tightness of the butt joint of the steel pipe cannot be guaranteed, which will lead to poor welding effect and increase the possibility of fracture at the weld during use; 2. The general butt welding method requires manual hand-held welding equipment after two square steel pipes are butt jointed Welding the welding place, this welding method is inefficient, and needs to constantly move the pipes to make them butt joints, which increases the burden on the staff
