Onsite Metal Stitching and Metal Locking for Repair of Cracks

Cracks in cast iron are developed due to excessive stress beyond its tensile strength or due to accident. The heat related cracks and cracks due to impact are quite common in case of engine blocks, casing of turbo charger, compressors and mechanical equipment.

The repair of cracks in cast iron has been tried by the different process and methods especially in case of cracks in the engine blocks. The welding process for the repair of the cracks is not always successful due to excessive heat generated. It is observed that even the center line of main journal housings gets disturbed and looses alignment.

RA Power Solutions undertakes repair of cracks by cold process i.e. metal locking and metal stitching. The metal lock and metal keys are sourced strictly as per the metallurgy of the broken casting and are inserted in a specific process.
It is observed that the repair of cracks by metal stitching process is successful in comparison to conventional welding method.
