Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention provides an MAG welding system for narrow-gap welding of a blade grid type partition. The MAG welding system comprises a bearing table, a rotation position-changing mechanism, a plurality of clamps, an operating mechanism and a welding device, wherein the rotation position-changing mechanism comprises a base and a rotary disc rotatably arranged on the base, and the clamps are mounted on the rotary disc. During welding, to-be-welded workpieces are respectively clamped to the clamps, the positions of the clamps are adjusted, the welding device is moved to a preset position through the operating mechanism, the welding device is started to perform welding, the rotary disc rotates to move the next workpiece in position after the welding of one workpiece is completed, the welded workpiece is taken off, and the process is repeated sequentially. The MAG welding system has the advantages that position adjusting only needs to be performed when the workpieces are mounted for the first time, subsequent workpieces can be directly clamped to the clamps, and work efficiency can be increased effectively.

Description

technical field [0001] The invention relates to welding technology, in particular to a narrow-gap MAG welding system for cascade partitions. Background technique [0002] Molten active gas shielded arc welding (MAG) is mainly used for narrow gap welding of cascade diaphragms, for example, welding of shrouded cascades of steam turbine units and inner and outer rings of diaphragms. At present, in the welding process, the workpiece is generally fixed first, and the position is adjusted, and then the welder moves to the designated position for welding. Therefore, it is necessary to fix and adjust the position of the workpiece many times during the welding process, resulting in low efficiency. Contents of the invention [0003] Based on this, it is necessary to provide a narrow-gap MAG welding system for cascade diaphragms that can effectively improve work efficiency. [0004] A narrow-gap MAG welding system for a cascade diaphragm, including: [0005] bearing platform; [...
