Embodiment Construction
[0026] The specific implementation and effect of a welding method for increasing material size according to the present invention will be described in detail below in conjunction with preferred embodiments.
[0027] A welding method for increasing material size provided by the present invention mainly includes the following steps:
[0028] 1) Confirm the surface of the part to be welded;
[0029] 2) The alloy sheet of the size required for the part is processed by wire cutting;
[0030] 3) Grinding the alloy sheet to clean the oxide film and improve the surface roughness;
[0031] 4) cleaning dust and oil stains and drying the alloy sheet after cleaning;
[0032] 5) The alloy sheet is fixed on the position to be welded by resistance spot welding, wherein the spot welding current is 30A, the spot welding angle is 50°, and the spot welding is carried out around the alloy sheet, and the distance between the welding spots is 8mm;
[0033] 6) Apply brazing material and smear flo...

Abstract
The invention relates to the technical field of non-traditional machining, in particular to a welding method for increasing material dimension. According to the welding method, an alloy sheet, made ofthe same material with a matrix alloy, of the needed dimension is machined in a wire-electrode cutting manner, the surface of the alloy sheet is polished, an oxidation film is removed, the oxidationfilm on the surface, to be welded, of a part is removed, the surface, to be welded, of the part is cleaned and dried, and the alloy sheet is spot welded and fixed to the to-be-welded portion in an resistance pot welding manner; then, after a brazing material is smeared and a flow stopping agent is smeared at the position nearby a weld joint zone, the brazing material and the flow stopping agent are dried, vacuum brazing is conducted, vacuum brazing heating in a vacuum brazing furnace, temperature preservation and cooling are conducted, and finally weld joint detection and machining are conducted on the welded portion so that the dimension of the part can be restored. By the adoption of the welding method for increasing material dimension, the part of a smaller dimension can be restored, the number of scrapped parts is reduced, cost is saved, and the production yield is improved.
Description
technical field [0001] The invention relates to the technical field of special processing, in particular to a welding method for increasing material size. Background technique [0002] During the processing of a blade edge plate, if the size is too large, it can be further processed until the part size meets the requirements. However, if the part size is too small, and the design requirements are too small, the size is unacceptable, and the part will be scrapped. Therefore, there is an urgent need to find a suitable method so that the parts are not discarded after being repaired when they are about 1mm smaller, and can also be used in parts that require slightly lower material strength. [0003] In view of this, the present invention provides a welding method for increasing material size. Contents of the invention [0004] The main purpose of the present invention is to solve the problem that the wear-resistant block falls after brazing, prevent the solder from flowing an...
