Embodiment Construction

[0053] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0054] Embodiments of the present invention: as figure 1 As shown, a welding system for girth welding is disclosed, which is mainly used for welding workpieces whose welding seam is located inside the pipeline, such as welding and fixing flanges on both sides of the shell pipe of a submersible pump. Specifically, such as figure 1 Shown is a shell pipe 100 of a submersible pump to be welded and an upper flange 200 and a lower flange 300 located at both ends of the shell pipe 100. The inner side wall of the upper flange 200 is provided with a flange stop ring 202, and the lower flange The inner side wall of 300 is also provided with a corresponding flange limit ring, one end of the shell tube 100 abuts on the flange limit ring 202 of the upper flange 200, and the other end abuts on the limit r...

Abstract

The invention discloses a positioning device, a welding system and a welding method. The positioning device comprises a supporting table used for supporting a workpiece to be welded, a pressing mechanism mounted above the supporting table and a driving mechanism used for driving the pressing mechanism to move close to or away from the supporting table, the positioning device further comprises a first flange positioning device and a second flange positioning device mounted between the pressing mechanism and the supporting table in a spaced manner in the up and down direction, compared with theprior art, through the first flange positioning device and the second flange positioning device, an upper flange and a lower flange are positioned, it is ensured that after the upper flange and the lower flange are welded, thread holes are opposite, finally, through the pressing mechanism, the positioned upper flange and the positioned lower flange are pressed and fixed to a shell pipe, it is ensured that in the welding process, the flanges and the shell pipe are axially pressed and positioned, the malposition in the welding process is avoided, and positioning welding of an annular welding seam is facilitated.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a positioning device, a welding system and a welding method for processing annular gaps. Background technique [0002] The submersible pump is a water-lifting equipment in which the motor and the water pump are submerged into the water. It has the advantages of simple structure, high energy saving, low noise, safe and reliable operation, and convenient installation and maintenance. It can be applied to various water-lifting occasions and has a huge market demand. [0003] During the production process of the submersible pump, the casing pipe of the submersible pump and the flanges arranged at both ends of the casing pipe generally need to be welded into one. Since the welding seam at the welding position of the casing pipe and the flange is an annular gap, its welding is difficult. At the same time, it is necessary to simultaneously locate the positional relationship between the...
