Friction Welding
15
Manufacturers of turbochargers had conventionally
used inertia friction welding techniques to join
the investment cast, Inconel wheel to the carbon
steel shaft. Although this joining method
produced a joint of adequate strength, the
post-weld machining, grinding and heat treatment
operations were expensive and time consuming. An
alternative welding process using EB welding has
been adopted by a number of leading turbocharger
manufacturers.
