Abstract
The invention discloses a welding process for reducing welding deformation of a tower side flange and a window, which comprises the following steps: and symmetrically welding the window body to a tower side flange, welding the window body and the tower side flange into an integral structure, and welding the integral structure to a tower side plate. The invention can effectively solve the deformation problem in the welding process of the impeller side flange, the window and the stator bracket, and realizes that the tower side flange and the window body have no deformation after being welded to the stator bracket. Firstly, the window body is welded to the tower side flange, the deformation is small after welding and shaping is convenient, and the window body is prevented from being welded to the side plate of the tower of the stator bracket. The window body is welded to the tower side flange, so that the deformation of the tower side flange and the deformation of the window body can be effectively reduced.
Description
Technical Field
The invention belongs to a welding process, and particularly relates to a welding process for reducing welding deformation of a tower side flange and a window.
Background
The welded structural part is an important component in mechanical manufacturing, and parts with complex structures can be produced and manufactured at low cost through a welding process. With the increasing requirements of the machining industry on the precision of parts, the post-welding deformation of a welded structural part becomes one of the main problems restricting the precision of the parts.
The current welding process is as follows: firstly, directly welding a window body and a stator; and secondly, welding the tower side flange and the window body. The welding process has the following disadvantages: after the window body is welded to the stator support, the deformation is easy to generate, and the shaping is difficult and not in place; the tower side flange is deformed during the second welding step due to the deformation of the window body. At present, two methods for reducing deformation after welding are mainly adopted: shaping the structural member through external force after welding; and the deformation of the structural part is prevented by utilizing the tool clamp for supporting. However, the weld distortion cannot be improved significantly by these two methods.
Disclosure of Invention
The invention aims to provide a welding process which can solve the problems of large deformation and difficult shaping after welding in the prior art and can reduce the welding deformation of a tower side flange and a window and door.
According to one aspect of the invention, a welding process for reducing welding deformation of a tower side flange and a window door is provided, and comprises the following steps:
the window body is symmetrically welded to the tower side flange,
welding the window body and the tower side flange into an integral structure,
welding the integral structure to the tower side plates.
In some embodiments, the window is a frame-like structure.
In some embodiments, the tower side flange is of a ring plate structure, and the window tower side flange joint is provided with a groove.
In some embodiments, the thickness of the tower-side flange is greater than the thickness of the window.
In some embodiments, the tower-side flange is a welded structure.
The beneficial effects are as follows: the invention can effectively solve the deformation problem in the welding process of the impeller side flange, the window and the stator bracket, and realizes that the tower side flange and the window body have no deformation after being welded to the stator bracket. Firstly, the window body is welded to the tower side flange, the deformation is small after welding and shaping is convenient, and the window body is prevented from being welded to the side plate of the tower of the stator bracket. The window body is welded to the tower side flange, so that the deformation of the tower side flange and the deformation of the window body can be effectively reduced.

Fig. 2 is a schematic view of the window structure of fig. 1.
Detailed Description
Fig. 1 schematically shows a welding process for reducing welding deformation of a tower-side flange 1 and a window and door according to an embodiment of the present invention, which includes the following steps: symmetrically welding the window body 2 to the tower side flange 1; welding the window body 2 and the tower side flange 1 into an integral structure; the whole structure is welded to the tower side plates 3.
The window body 2 is of a frame-shaped structure. Specifically, the window body 2 is rectangular, and an oval through hole is formed in the middle of the window body 2. The tower side flange 1 is of a ring plate structure. The tower side flange 1 is of a welding structure and is convenient to manufacture. The connection part of the window body 2 and the tower frame flange is provided with a groove, so that the welding degree can be ensured. The thickness of tower side flange 1 is greater than the thickness of window body 2, guarantees overall structure fastness.
The invention can effectively solve the deformation problem in the welding process of the impeller side flange, the window and the stator bracket, and realizes that the tower side flange and the window body 2 have no deformation after being welded to the stator bracket. At first with window body 2 welding tower side flange 1, the deformation is less and be convenient for the plastic after the welding, avoids welding window body 2 to stator support tower side curb plate 3 earlier. With window 2 welding to tower side flange 1, can effectively reduce the deformation of tower side flange 1 and window 2.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
