Welded component postwelding heat treatment process

Abstract

The invention discloses a welded component postwelding heat treatment process including the following steps: 1) postwelding heat treatment is required to preferably adopt a method of heating in a furnace, and the heat treatment furnace is required to meet relevant provisions of GB9452; and under a condition of accumulation of the corresponding relationship value of the furnace temperature and heated components, the temperature of the furnace is generally allowed to calculate the temperature of the heated components during furnace internal heat treatment; 2) the heated components are required to be neatly placed in an effective heating area in the furnace, the furnace internal heat is guaranteed to be evenly circulated, and during flame furnace internal heat treatment, flame is required to be avoided from directly spraying onto the workpieces; and 3) for preventing generation of the restraint stress and deformation, a support of the heated components is required to be reasonably placed, and necessary supporting and other tools are required to be additionally added on large thin-wall members and components with great structure and geometry size changes so as to increase the stiffness and balancing stability. The technical problem to be solved comprises that provided is the welded component postwelding heat treatment process; the heat treatment process is simple in method and can make a welding effect better and more stable.

Description

technical field [0001] The invention relates to a post-weld heat treatment process for a welded component. Background technique [0002] At present, the post-weld heat treatment process of welded components is relatively complicated, and there is no unified specification and standard, resulting in uneven quality of welded components produced, and many repeated processes also make production efficiency low, increase the labor burden of workers, and make products market competitiveness is not high. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and omissions during operation, and may even cause serious consequences. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a post-weld heat treatment process for welded components, which is simple and can make the welding effect better and more...
