1. Welding repair.

Excavate the metal in the defective area, use the same or compatible electrode as the base metal to weld the defective area, smooth after welding and perform post-weld heat treatment.

  

2. For castings subjected to liquid or gas pressure, partial or overall impregnation treatment can be carried out to improve the sealing performance of the casting.

 

3. Important parts can be processed by hot isostatic pressing to eliminate looseness in the casting.

 

4. When the porosity exceeds the acceptance conditions and cannot be remedied, or the casting cracks during solidification, cooling or heat treatment, it should be scrapped.
