Crack Repair by Metal Surgery – RA Power Solutions

RA Power Solutions Pvt. Ltd. was called by a leading forging company based in the western part of India, manufacturing open forgings for heavy engineering plants. One of the operations involved the use of a clear space pneumatic hammer, which they imported from Massey of the UK.

Due to constant use of the forging hammer and its age, the pneumatic chamber of the hammer developed a crack measuring 69 inches. The whole plant, due to the non-operation of this critical equipment, was on standstill. The pneumatic chamber is manufactured out of grey cast iron. The company tried to repair the crack by the

welding process and engaged a leading company to execute the repairs. The crack repair of the cast iron pneumatic chamber was not successful. RA Power Solutions Pvt. Ltd. was called to repair the crack through the metal surgery process.

Metal Surgery 

RA Power Solutions Pvt. Ltd. initially carried out magnetic particle test (MPI) and dye penetrant test of the cast iron pneumatic chamber to check the exact length and the profile of the crack developed. The paint, including red oxide, applied on the cast iron pneumatic chamber, was removed completely. The crack of 69 inches was repaired by our technicians by metal stitching and the metal locking process.

The keys, master metal locks, and all consumables used for metal surgery were imported from the UK. After the completion of metal stitching and metal locking operations, the chemicals were applied to stop the air leakage from the pneumatic chamber.

This process of metal surgery, followed by us for repair of a crack in cast iron, is cold, no heat is generated, and is a proven method for successful repair of a crack in cast iron casting.

We have more than 45 years of experience of executing crack repair in cast iron by metal surgery, crack repair in cast iron and have experienced technicians available to execute the crack repair onsite in minimum time and cost.

RA Power Solutions has successfully executed more than 600 jobs for the repair of housings that are damaged due to the development of cracks or casting that breaks into pieces. The advantage of metal locking and metal stitching is that in case a large area of casting is damaged, a new piece having similar metallurgical properties is cast and metal stitched on to the parent body of the casting.
