Cracked Cast Iron Repair | Metal Stitching of Damaged Casting

No engineering plant does not have welding equipment and qualified welders. In case of damage or development of cracks in heavy and large components, we have experienced that the first reaction of the factory manager or a ship engineer is to repair cracked damaged components by welding. In 90% of cases, welding repairs for cracks fail and even worsen the crack and damage to the casting, leading to total rejection beyond the repair stage.

As a heavy engineering repair company with nearly five decades of experience. We recommend metal locking and metal stitching for repairs. This includes marine engine components, heavy cast iron, and steel castings. No heat is used or generated; hence, there is no need for machining in most cases.

Advantages of Crack Repair by Metal Lock and Metal Stitching:-

• Our technicians can often repair large equipment without disassembly, reducing downtime and dismantling costs.
• Metal stitching can repair cracks even in areas with limited working space. Our technicians use pneumatic tools in different designs and profiles, allowing them to access confined areas and carry out precise crack repairs where conventional equipment may not fit.
• No technology in the world can replace the repair of large, damaged castings. Metal stitching and the metal locking process remain the most reliable methods.
• We have recently replaced a damaged portion of the Wartsila 18V32 engine block measuring 3200 mm x 900 mm.
• Our technicians recast, machined, and fitted the damaged inspection windows using metal locking and metal stitching.
• Repairs are possible onsite; we deploy our technicians with portable equipment and consumables. The job is done onsite.
• The crack repair by metal lock and metal stitching of the damaged casting is possible even while the vessel is sailing. There is no need to hold the vessel to complete the repairs.
• The cost of crack repair and repair of damaged casting plays a very important role in this time of recession.
