Embodiment Construction

[0021] The following will be combined with Figure 1-5 The specific embodiments shown are used to describe the present invention in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0022] The anti-deformation welding process for large and long box-shaped structural parts includes the following steps; figure 1 and 2 as shown,

[0023] 1) Adjust the position of the large and long box-shaped structural part: place the large and long box-shaped structural part 1 formed by the combination of the vertical plate 2 and the cover plate 3 horizontally according to the vertical plate 2;

[0024] 2) Adjust the welding method: take the weld seam as the benchmark, the weld seam as the benchmark here is a set of weld seams to be welded, and use the upper end surface of the vertical plate 2 as the walking support surface of the semi-automatic welding trolley 4, so that the se...

Abstract

The invention provides an anti-deformation welding process for a large and long box-shaped structural part. By adjusting the position of the large and long box-shaped structural part, adjusting a welding method, optimizing a welding path and a welding sequence and adjusting the welding parameters, the welding deformation control problem of a large and long straight weld joint is solved, automatictracking can be completely achieved, manual intervention is not needed, and the horizontal requirement and the labor intensity of welding operators are reduced.

Description

technical field [0001] The invention belongs to the technical field of welding technology, and in particular relates to an anti-deformation welding technology for large and long box-shaped structural parts. Background technique [0002] The fixing method of large and long box-shaped structural parts is mainly to adopt welding connection. The existing welding arrangement methods of large and long box-shaped structural parts during the welding process are as follows image 3 Shown, vertical plate 2 is vertical, and cover plate 3 is horizontal. The following problems exist when using semi-automatic welding trolley for welding: on the one hand, the height of the trolley is 290mm, plus the height of the welding torch, it is impossible to make the welding torch side suction on the vertical plate for welding; on the other hand, the welding operation of large and long straight box-shaped structural parts is When working on multiple platforms, the working platform is composed of mult...
