GOLD WELDING ALLOYS FOR REPAIR OF BEARING HOUSINGS
Bearing housings are subject to heavy pressure by the shafts causing wear and thereby loosing efficiency . Such worn bearing housings can be reclaimed by using the MMA or MIG/MAG Welding process.
- CAST IRON BEARING HOUSING
Use GOLD 420
- STEEL BEARING HOUSING
Use GOLD 710
Cost of Weld repair is only approx. 10 % of the cost of a new housing. Lifetime of housing repaired with GOLD 710 increases lifetime.
