In case of damage to engine components or cracks, RA Power Solutions repairs them onsite by metal stitching or metal lock surgery. We lead this field because we use master lock, masterpiece, keys, and high-quality consumables imported from the UK.

Our technicians have extensive experience. They can execute crack repairs and repair damaged casting components while the vessel is sailing.

Following is the process of metal locking, metal stitching, and its advantages.

Process of Metal Locking, Metal Stitching:

Experts accept the metal stitching process as the method for repairing all cracked, broken, and damaged castings in cast iron, aluminium, and steel.

The Stitching Process:

• First, we identify visible and invisible cracks.
• We clamp the parts together to restore them to their original position.
• We make a rectangular hole across the fractured portion.
• This hole is made by drilling and chipping.
• We insert the master lock, a large rectangular key of special metal, into the hole.
• We insert locking pins alongside the master lock. These pins provide a tight and secure master lock.
• We insert a length of metal stitching keys on the sides of the master lock. These keys prevent the locking pins from falling out when the casting faces high vibrations.

Advantages of Metal Stitching:

• No heat stress is induced
• No Distortion occurs
• In many instances, machining is not required
• Invaluable in emergencies
• Reduces downtime
• Gas/ Liquid proof repair

At RA Power Solutions, we specialise in cast iron metal surgery and crack repair. We use advanced techniques that restore structural integrity and performance without the drawbacks of traditional welding methods.

  A leading shipping company operating in the Middle East approached us for assistance. One of their auxiliary engines, a Daihatsu 6DK20, met with an accident. A connecting rod bolt failure breaks the engine block window, where the cover is fixed, into multiple pieces.

RA Power Solutions Pvt. Ltd. technicians prepared a rough drawing of the broken cast-iron area of the engine block, as shown below.

Cast Iron Metal Surgery

Metal surgery refers to a group of cold repair techniques designed to restore cracked or broken cast iron parts without excessive heat. Unlike welding, which generates heat and can distort the component, metal surgery methods preserve the material’s original alignment and dimensions. These processes include metal stitching, metal locking, cold stitching, brazing, fusion techniques, and controlled stress relief treatments.

Since the time was short, we manufactured a casting measuring 15 x 15 inches, and two technicians boarded the vessel. The job of repairing the cast-iron engine block was executed in a recorded minimum time. The engine is performing satisfactorily.

We have all the latest tooling available for the repair of cast iron.  The parts of the diesel engine are to return to their original shape and profile. The metal stitching and metal locking process, followed by us to repair the cast iron, gives more strength than the original casting.

It is proven that the repair of cracks in cast iron or cast steel castings is successful by metal stitching and metal locking process in comparison to the old welding process that was followed.

The advantages of crack repair by metal stitching and metal locking process are as follows:

• Metal stitching and metal locking processes repair cracks in engine blocks, cylinder heads, and turbines on-site without disassembling the equipment. This process of repair saves downtime and is cost-effective.
• The metal locking and metal stitching process provides an excellent expansion joint for engine parts such as cylinder liners, crankcases, and cylinder heads, which are subject to thermal and mechanical stresses. The main advantage of repairing cracks using the metal stitching and metal locking process is that the process develops no stresses and maintains alignment with the original surfaces because it produces no heat and causes no distortion.
• The procedure and process of repair of cracks by metal stitching and metal locking are accepted by various classes and inspection agencies.
• The process of metal locking and metal stitching is cold, no heat is generate and in most cases, there is no need to replace heavy and expensive parts.

Metal Stitching Of Engine Block

RA Power Solutions Pvt. Ltd. undertakes the repair of cracked or damaged engine blocks using metal locking, metal stitching, and the metal surgery process. It is possible to repair damaged or cracked engine blocks on-site that are manufactured from the following base metals.

• Cast steel
• Aluminium casting
• Ductile iron
• Cast iron

With the introduction of modern technology and processes. Welding does not suit the repair of cracks in heavy-duty cast iron components because the welding process generates heat and unwanted stresses. It cause serious damage to the cast iron components.

The engine block repair by metal locking, metal stitching of the engine block, and the metal surgery process is a proven method of repair of cracks or damaged heavy components.
