An Evaluation of Waspaloy Expander Blade Tip Weld Repairs
Keyword(s):
The abrasive wear of blade tips in fluid catalytic cracking unit power recovery turbines is one of the principal ‘failure’ mechanisms for the parts. The occurrence of tip wear considerably shortens the effective life of the blade: generally well below the anticipated mechanical life of the component. This paper details the evaluation of mechanical properties and metallographic characteristics of a fully re-heat treated, Waspaloy on Waspaloy weldment for blade tip repair that will allow re-utilization of the blades.
