Metal lock & metal stitching is the process by which cracks or damaged broken cast iron, bronze, and aluminum components can be repaired. We have been extending services for metal locking and metal stitching for turbine-generating equipment, large water pump, forging equipment and various components of high capacity diesel generating sets. In fact all these years we have been regularly repairing cracks and seriously damaged components manufactured out of aluminum, bronze and cast iron by metal locking and metal stitching process. We us latest technology, process and consumables for succesful and guranteed repairs.
All the repairs executed by us are onsite and without disassembly of the main equipment.

The procedure for metal locking and metal stitching of damaged components followed by RA Power Solutions is as following:
- A drilling fixture is attached at right angles to the crack. A hole pattern is drilled and repeated at intervals of 3/4" to 1-1/4" inches apart.
- The metal between each drilled hole is removed with the help of pneumatic tools to form a slot. The stock removed is narrower than the drilled hole, thus forming a serrated opening.
- Preformed locks of high tensile alloy are inserted into the drilled slot. These locks are peened into the slots, one on top of the other (overlapping), to a depth limited by the casting thickness and determined by the strength required.
- After the locks are installed, holes are drilled and tapped and threaded fasteners are applied. These are spotted along the entire length of the crack, overlapping one another. Their purpose, in part, is to fill the fracture with new metal and provide a pressure seal.
- The entire repair area is peened flush and finish ground. Painted if required.
The Metal Locking technique can be used to repair everything from casting faults, broken machinery and improper machining to intricate items such as marine engines and gears. We are able to work on a wide array of materials including work-hardened and heat-treated items.
