On site  Metal stitching  and  metal locking  is a precise mechanical method of making permanent repairs to broken casting and machine parts. Procedure of On site Metal Stitching and Metal Locking Drilling fixture is attached of right angles to the crack. A hole pattern is drilled and this is repeated at intervals from ¾ to 1 ¼ inches apart in this process of  metal stitc hing metal locking . Metal between each drilled hole is removed by ripping it away with pneumatic tools to form a slot. The stock thus removed is narrower than the drilled hole, thus forming a serrated opening. Preformed locks of high tensile alloy are inserted in to the slot of  metal locking and  metal stitching  process . These locks are peened into the slots, one on top of the other, to a depth limited by the casting thickness and determined by the strength required. After the locks are installed, holes are drilled, tapped and threaded, fasteners are applied. These are spotted along the entire length of the crack,
