Abstract

The invention discloses a heating frock of narrow-gap clapboard welding and a using method thereof, and aims at solving the problem in the prior art that when steam turbine clapboard fixed blades arewelded, the finished product rate is low due to over-high welding line cooling speed because welding lines cannot be heated. In the heating frock of narrow-gap clapboard welding, an arc support is provided with multiple flame mouths, the arc support is arranged in the same shape as a workpiece to be processed, meanwhile an installation hole is formed in the arc support according to the specific processing position of the workpiece to be processed, in this way, the welding line of the workpiece to be processed can be heated precisely, and the finished product rate is ensured; besides, the workpiece to be processed is placed correspondingly before processing, and the processing efficiency is improved; the heating frock of narrow-gap clapboard welding and the using method thereof are applicable to the field of welding processing.

Description

technical field [0001] The invention relates to the field of welding processing, in particular to a heating tool for welding narrow-gap partitions and a use method thereof. Background technique [0002] In the process of steam turbine processing, different processing tools are required to process the corresponding parts. Processing tooling has a major impact on the quality of the product. Among them, the welding of steam turbine stator blades, because the welding material material in the welding process needs to maintain a certain temperature during the welding process to prevent it from cooling too quickly to cause weld cracks, and the welding seam needs to be continuously heated during the welding process. This problem is not paid attention to in the production process, resulting in poor product quality and low yield. Some existing ones may use manual heating to maintain the weld temperature, but this is laborious and troublesome to operate, and due to human operation pro...
