How to Repair a Shaft Using Forming Techniques

In this short video, you will learn how to repair a #wornshaft using #Belzona1111 and a #metalformer to rebuild a damaged shaft using forming techniques. Our rebuilding solutions for damaged shafts offer simple applications by reducing hot work and cutting downtime.

Shafts become worn and damaged due to vibration, rubbing, abrasive contaminants and corrosion. Where it is impractical to strip a shaft, Belzona metallic polymers can repair in-situ without the risks that result from welding procedures. Worn and damaged shafts can be repaired in situ, limiting the downtime and lost production costs which can be incurred.

Materials used: 
To repair this damaged shaft, we used Belzona 1111 (Super Metal) and Belzona 9411 (Release agent).

How to guide:
Step 1: Clean damaged area of the shaft
Step 2: Undercut the repair area and roughen the profile with a grinder 
Step 3: Clean the prepared area to remove all surface contaminants
Step 4: Apply Belzona 9411 to the internal surface of the former
Step 5: Tape off the repaired area and apply Belzona 9411 to the surface outside of the repair area. 
Step 6: Remove tape 
Step 7: Mix thoroughly Belzona 1111
Step 8: Wet out internal surface of former with Belzona 1111
Step 9: Firmly apply Belzona 1111 to the repair area on the shaft
Step 10: Form central peak to avoid air entrapment 
Step 11: Position both part of the former and secure with bolts
Step 12: Clamp in position and remove excess
Step 13: Remove bolts after cure and remove former
Step 14: Smooth out surface of the repair and clean area
