As laser cladding utilization reaches maturity and becomes more widespread, repairers are expanding the range of applications and keep always testing the limits and benefits of laser cladding technology.

Over the past years, we have seen an increase in repairs of alternator or electric motor rotor journals by laser cladding.

Alternator rotors face wear, overheating, or damage, usually in the way of bearing journals from continuous operation, overspeed, or poor lubrication. Repair of alternator rotors with conventional welding methods can be risky. That is because excessive heat input may damage alternator copper winding and affect alignment and overall dimensions alteration.

Laser cladding is the welding method with the lowest heat input on the part; therefore, it is by far the safest and most suitable repair solution for repairing alternators or electric motor rotors. Notably, it minimizes part distortion and the risk of damaging the rotor winding.

Of course, in addition to low heat input, laser cladding enjoys many more advantages than other welding methods. Together with the low dilution of material, the ability to apply thick or excellent coatings and various coating material applications with higher mechanical properties. Equally important, hardness and high corrosion resistance enable us to improve rotor properties and prolong its operational life.

At our workshop, we operate two laser cladding machines and can accommodate even the largest rotors with a length of 10mtrs and a weight of 20tns.

 

This, coupled with our in-house machining capacity with heavy-duty lathes and cranes, made us the preferred alternator recondition station. We currently serve customers from shipping, energy, heavy industry, renewable sectors, or even OEMs who all have such equipment.
