Repair by internal coating of hollow shaft

How do you save a lot of time, energy and material?

Very simple: Repair your parts!
For this job, we processed a hollow shaft from the mining industry by applying an internal coating using laser powder cladding. After our customer had identified and worked out damage on the inside, we rebuilt the inside diameter from 330 mm to 315 mm. The customer then carried out the final machining by turning to the final dimensions so that the hollow shaft was quickly ready for use again.

Keyfacts:

• Hollow shaft from the open-cast mining / conveyor technology sector
• Weight: approx. 2.6 tons
• Size: 1.80 x 1.25 meters
• Basic material: C45
• Filler material: Nickel-chrome-based alloy + Iron-based alloy (approx. 55 HRC)
• Filler material ensures high corrosion and wear resistance
• Laser powder cladding with a modern robot-assisted laser system with ALOpowder^ID internal coating optics and ALOpowder^zoom zoom optics

✔ Repair saves a lot of time, energy and material.

We have created a video about the internal coating of the hollow shaft and published it on Youtube:
