What to do if castings are deformed during production and processing

existPrecision castingDuring the manufacturing process, the polishing method should be used to clean the surface defects of mechanical equipment. After polishing, the specifications of the castings should be effectively adapted to the dimensional tolerance standards of the casting specifications. If the casting is deformed during the production and processing, how to correct it? In fact, it can be used Mechanical correction, I will share it with you below!

During the application process, precision castings can be directly repaired through welding supplementation. When mechanical equipment uses tungsten arc welding, the welding supplementary surface area and welding supplementation depth should comply with its standards. Here, the welding supplementary surface area in mechanical equipment refers to the expanded surface area .

same placePrecision castingThe welding supplement should not exceed 3 times. The distance between the castings at the edge of the welding zone involves the reverse welding zone. Remember not to be less than the sum of the diameters of the two adjacent welding zones. Castings supplied in a heat-treated tempered state should be processed in their original state after welding Heat treatment.

Precision castings after heat treatment and tempering should also be able to test their mechanical properties. The surface area of ​​the argon arc welding zone of the casting shall not be less than 2cm2, and the distance between the mechanical welding zones shall not exceed 100mm. Heat treatment and tempering shall not be performed during use, but the precision casting shall not exceed 5 .

Precision castingThere must be no cracks or lack of welding in the welding supplementary area. In all welding areas, castings are allowed to have pores with a diameter not exceeding 2mm, a wall thickness not exceeding 1\/3 or a mixture of 3, and the margin of mechanical equipment not exceeding 10mm.

Precision castings that work in corrosive media and atmospheres, mechanical equipment are not allowed to use flux when welding and replenishing, and dense precision castings must be penetrated and replenished according to allowed standards.
