Coat­ing brake disks

The auto­mat­ed coat­ing of thou­sands of brake disks per day depends on the right process mon­i­tor­ing. The main chal­lenges here are reli­able detec­tion of safe­ty-rel­e­vant devi­a­tions at very high feed speeds, long-term stor­age for trace­abil­i­ty, max­i­miza­tion of sys­tem avail­abil­i­ty through ear­ly detec­tion of devi­a­tions in the process and the input material.

The > 4D.watch­er with the patent­ed sen­sor > 4D.TWO® pro­vides a holis­tic view of the sta­tus of the process and allows sim­ple, albeit com­plex, record­ing of this demand­ing process.

8 power drops from 16 kW to 13 kW (from left to right: 2, 4, 8, 16, 32, 64, 128, 256 ms)
8 pow­er drops from 16 kW to 13 kW (from left to right: 2, 4, 8, 16, 32, 64, 128, 256 ms)
Deviations in the carrier gas can be effectively detected by using various algorithms
Devi­a­tions in the car­ri­er gas can be effec­tive­ly detect­ed by using var­i­ous algorithms
A significant drop in signal strength is a clear indicator of a decrease in powder quantity, which is followed here by an increase in power level
A sig­nif­i­cant drop in sig­nal strength is a clear indi­ca­tor of a decrease in pow­der quan­ti­ty, which is fol­lowed here by an increase in pow­er level
The drop in power can be observed at all wavelengths
The drop in pow­er can be observed at all wavelengths

Laser cladding presents chal­lenges, espe­cial­ly when it comes to mon­i­tor­ing the laser process. Pre­cise con­trol and mon­i­tor­ing of the process para­me­ters – such as laser pow­er, scan­ning speed and pow­der feed – is cru­cial to ensure uni­form and high-qual­i­ty coat­ings. Even the small­est devi­a­tions can affect the coat­ing qual­i­ty, result­ing in uneven lay­ers, poros­i­ty or even mate­r­i­al defects.

Chal­lenges

Process length and deviations

  • Long process in one pass: unde­tect­ed process devi­a­tions and a high pseu­do error rate
  • Large num­ber of process devi­a­tions: a mul­ti­tude of influ­ences make trou­bleshoot­ing difficult
