MarineShaft recently acquired another laser cladding system, which is performing exceptionally well. The repair case described earlier was carried out with this new equipment.

CAPACITY BOOST

With two laser cladding systems, we ensure capacity for urgent requests, and most of our laser cladding repairs are related to breakdowns where fast action is crucial.

Another important reason for this expansion is to provide more repair possibilities. This new system has an extended reach in cavities and is easier to move around with its continuous tracks.

The robot arm can lift 45 kg of equipment compared to the other systems 10 kg capacity.  

Urgent Crankshaft repair

MarineShaft engineers worked throughout the weekend to finish a crankshaft repair quickly.

Case:

The crankshaft had sustained damage to the coupling end and the customer had previously made a temporary repair by shrink fitting a ring on the coupling end.

Now the customer had to find a permanent solution, and they contacted MarineShaft to discuss our repair proposal.

MarineShaft specialize in laser cladding and they recommended a repair by laser cladding to rebuild the surface to original dimensions.

Upon receiving the crankshaft in our workshop, MS meticulously skimmed the surface to prepare for laser cladding and NDT.

The laser cladding process of rebuilding the coupling end began. In total, we applied 16 layers of Inconel 625, each adding 0,8 mm of material. After completing the laser cladding, MS machined the repaired surfaces, and a final NDT was carried out by an independent third-party company.

In just three days, MS repaired the crankshaft with approval from DNV.

MarineShaft has class approvals to use laser cladding on:

• Stainless steel
• Carbon steel
• Bronze
• Cast iron
