Abstract

The invention discloses a device and method for controlling a suspension welding seam root gap and welding deformation in a self-supporting mode. The device comprises a positioning block, upper rigid press blocks, a lower rigid press block and a forming groove. The positioning block comprises a positioning block body and a positioning part, wherein the positioning part penetrates through the seam root gap and is embedded in the forming groove. The upper rigid press blocks are symmetrically installed on the two sides of the positioning block body, the lower rigid press block is provided with provided with an inward-concave part matched with the forming groove, and the forming groove is formed in the inward-concave part. Magnets are installed in the upper rigid press blocks and the lower rigid press block. The invention further discloses the method with the device for controlling the suspension welding seam root gap and the welding deformation in the self-supporting mode used. The device for controlling the suspension welding seam root gap and the welding deformation in the self-supporting mode is convenient to use, low in cost and high in adaptation, the transverse retraction and staggered edges of a welding seam can be controlled, the welding deformation can be reduced, and it can be ensured that the back face of the welding seam is good in formation.

Description

technical field

[0001] The invention belongs to the technical field of ship assembly and welding, and in particular relates to a device and method for self-supporting and controlling the gap at the root of a suspended weld seam and welding deformation. Background technique

[0002] High-speed ships at home and abroad are mainly welded by aluminum alloys. Because the elastic modulus and yield strength of aluminum alloys are small at temperatures above 200 to 300 degrees Celsius, the deformation resistance is poor; and the thermal conductivity and thermal expansion coefficient of aluminum alloy materials are large. , the welding high-temperature zone is wide, and the welding stress and deformation are relatively large. As a result, when these aluminum hulls are assembled and closed and other suspended positions are welded, the lateral shrinkage of the weld and the welding deformation are much larger than those of the steel section. Orthopedic treatment is required after weldin...
