Abstract

The invention relates to the technical field of casting, in particular to a method for repairing casting defects of castings, which comprises the following steps: step 1, cleaning the surface; step 2, repairing a defect part; thirdly, molten metal is prepared; fourthly, preliminary repairing is conducted; 5, secondary repairing is carried out; sixthly, the defect position is polished; 7, polishing the casting; defects on the surface of the metal casting are repaired, the strength of the metal casting is improved, the metal casting is not prone to deformation and long in service life, and the use quality of the metal casting is improved; the repairing operation is simple, the repairing time is short and the repairing effect is good; the number of recasting is reduced, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a method for repairing casting defects of castings. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the resulting object has a certain shape, size and performance. [0003] In actual production, castings will inevitably have defects. If smaller defects are also melted and recast, it will waste costs and reduce production efficiency. Therefore, such defects need to be repaired. Contents of the invention [0004] The object of the present invention is to provide a method for repairing casting defects, so as to solve the problems raised in the above-mentioned background technology. [0005] In order to achieve the above object...
