Crack Repair of Cast Iron by Metal Stitching/Metal Locking Process – RA Power Solutions

RA Power Solutions Pvt. Ltd. has recently undertaken the repair of a cast iron engine block, including crack repair, using the metal stitching and metal locking process. The engine block, which is made of cast iron, was broken from the window cover sitting area. The engine block was broken into pieces measuring approximately 330 × 420 mm.

Metal Locking of Steel Casting – RA Power Solutions

RA Power Solutions has undertaken onsite repair of engine blocks, compressors, and rotary equipment for the last 45 years. We feel that the repair cracks developed in cast iron and steel castings are repaired successfully by the metal locking and metal stitching process without losing the original profile.

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.
