Problems solved by technology

[0004] When the widely used girth welding machine system with the inner cavity of the pipe fittings is used for the inner girth welding of the pipe fittings, there are the following problems: First, due to the poor consistency between the diameters of the inner cavities of the pipe fittings, resulting in The positioning consistency is poor, so the positioning mechanism needs to be greatly adjusted when positioning different pipe fittings, so as to meet the high positioning requirements of inner ring seam welding; secondly, the feeding and adjustment mechanism is cumbersome
Due to the above reasons, it takes a long time to feed, position and adjust the pipe fittings to be welded each time
[0005] It can be seen that the current girth welding machine system that uses the inner cavity of the pipe fitting for positioning has the problem of low efficiency when used for inner girth welding

Abstract

The invention relates to an inner circular seam welding machine system and an inner circular seam welding method. The inner circular seam welding machine system comprises a welding gun for welding a welded joint between a pipe fitting and a welding part, a pipe fitting placing platform with a pipe fitting placing plane which is horizontally located, and a pipe fitting external diameter location device arranged on the tube placing platform, wherein the pipe fitting placing platform is used for placing a pipe fitting to be welded; and the pipe fitting external diameter location device is used for locating the pipe fitting with the external diameter of the pipe fitting on the pipe fitting placing platform.

Description

technical field [0001] The present invention generally relates to an inner ring seam welding machine system and an inner ring seam welding method, more specifically, the present invention relates to an inner ring seam welding machine system and a corresponding inner ring seam welding machine for welding the inner ring seam between a cylindrical pipe fitting and a flange member Welding method. Background technique [0002] Circular seam welding of pipe fittings is a common type of welding in welding technology. Ring seams are usually divided into inner ring seams and outer ring seams. Most of the circular seam welding machine systems currently on the market are used for welding the outer circular seam, which is usually positioned by the inner cavity of the pipe fitting. [0003] However, the requirements for welding the inner ring seam between the pipe fitting and the flange at a certain welding angle are relatively high, for example, the weld seam cannot be higher than the...
