Pistons
Piston grooves often wear out in working conditions where combustion occurs in the engine, and the pressure distribution affects the force acting on the ring, causing the ring grooves and groove sides to wear. This results in sealing problems and reduction in engine efficiency.
Laser Cladding allows us to rebuild the piston groove back to original clearance with cobalt-based alloys. This material can fusion bond with the piston grooves and provide more durability due to high wear resistance properties.
Original material: Cast Steel
Laser Cladded material: Cobalt based alloy
Results: Improved durability up to 30% (subjected to crew engine handling and maintenance)
Turbocharger Shaft Restoration
Due to its high rpm, turbocharger shaft journal and sealing grooves often wear out. All these clearances are very important to ensure the efficiency of your turbocharger. Running at such high speed requires clearances to be very tight, any errors may be catastrophic to your turbocharger.
Laser Cladding due to it’s low heat input but still able to provide an excellent fusion bonding makes it the perfect technology for repairing parts like this without causing any distortion or affecting the straightness of the shaft.

Steam Turbine Shaft Labyrinth Restoration
Steam turbines often suffer from corrosion, which can reduce the sealing capability and hence efficiency of the plant. In this scenario, the labyrinth was completely worn out and through laser cladding, labyrinths were able to be reconditioned back to it’s original size.
Laser Cladding with fusion bonding is able to build layer on layer to restore deep worn-out areas and re –machine components back to original size. With Laser Cladding, materials that are cladded are also much more resistant to corrosion thus adding durability to the part.

Coupling ID Restoration
Coupling ID was corroded and scored due to operation. Laser Cladding with low heat distortion capability can restore parts like this without causing a deformation to the part. Operations like these are simple and easy for laser cladding to work on.
Split Pump Housing Restoration
Due to the age of this pump housing (40 years old) and at the same time running in harsh condition, pump housing was badly corroded. Furthermore, the pump housing was out of production. Using laser cladding technology, LCS is able to restore the pump casing back to its original specifications.
Original material: Cast Steel

Crane Swivel Shaft Restoration
Parts that require strong bonding strength is perfect for laser cladding due to the fusion bonding nature. The thread was damaged and nut was unable to screw in. The screw was machined completely off in LCS premises and laser cladding back to original size. Thread was then tested to withstand a tensile load of 80T and proven to be successful. Currently the thread is being used onboard the vessel and operating as per normal usage.
Crankshaft Restoration
The crankpin area was worn down causing the piston rod to be loose. The crankshaft is a very delicate part which is subjected to many types of stress. Laser Cladding due to the small spot size, is able properly target the area that is to be cladded. Using laser cladding, 2mm of Inconel is cladded on the crankpin followed by final grinding to size. All the processes are certified and approved by Class (DNV GL).
Pump Shaft Restoration
Laser Cladding Technology can restore almost all kinds of pump shaft damages, from shaft OD to impeller ID and OD damages. Different materials are also used to suit and strengthen the durability of pump shafts.
The above are examples of laser cladding’s capabilities but are not limited to the library. Laser Cladding due to it’sversatility in material combination pair with low heat input and 6 axis robotic movement is able to provide a wide variety of solution for our customers.
