Embodiment Construction

[0019] Referring to the accompanying drawings, a welding method for controlling welding deformation and improving weld seam quality specifically includes the following steps:

[0020] (1) Select two metal plates 1 and 2 as the butt weldment, and according to the shape of the two metal plates 1 and 2, respectively open slopes of appropriate degrees on the upper and lower sides of the welding surfaces of the two metal plates 1 and 2 mouth;

[0021] (2) According to the materials of the two metal plates 1 and 2, select a suitable electrode and bake the electrode;

[0022] (3) Clean the surfaces of the two metal plates 1 and 2, and polish the grooves on the upper and lower sides of the two metal plates 1 and 2 until bright;

[0023] (4) Connect the groove on the upper side of the welding surface of one metal sheet in the two processed metal sheets 1 and 2 to the groove on the lower side of the welding surface of the other metal sheet, and use the baked welding rod for welding. F...

Abstract

The invention discloses a welding method capable of controlling welding deformation and improving quality of welding seams. By adopting deformation and reversible deformation (action force and counter action force) effect of materials and chamfering design of a welding surface, welding parameters and welding operation modes can be adjusted during welding, deformation risk of the materials during welding is reduced, and welding quality of the welding seams is improved, so that production efficiency during operation is improved, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of welding and repairing of metal plates and pipes (pressure vessel parts), in particular to a welding method that adopts a groove pattern and a welding method to control welding deformation and improve weld seam quality. Background technique [0002] In the prior art, the general material butt welding method is difficult to ensure that the material will not be deformed during the welding repair process without welding tooling. Contents of the invention [0003] The purpose of the present invention is to provide a welding method for controlling welding deformation and improving the quality of the weld seam. By adopting the groove pattern and using the action force and reaction force, not only the deformation can be controlled, but also the welding quality of the weld seam can be better improved. [0004] Technical scheme of the present invention is as follows: [0005] A welding method for controlling wel...
