A solid-state welding technique
Inertia welding is a solid state welding technique that actually forges metal together without causing or requiring a melt product to occur. It is capable of joining many metals and combinations of metals including many that experts say “can’t be joined”.

A bi-metal Transition is a part made up of two metals that are welded together with a high integrity weld. Frequently these metal combinations are ones that are considered not weldable with conventional methods.
A more detailed list of materials and combinations that have been successfully inertia welded is located here.

Common Industry Solutions
Inertia welding has become an industry standard in a number of applications and should be considered in 3 types of situations: as a cost reduction measure, where the present joining method is not entirely satisfactory, or as new part that is being designed.
DESIGN AND DEVELOPMENT
Inertia welding should be considered in design situations, especially where a unit is composed of two dissimilar metals and/or a complex shape which can be broken down to simple components.
Problems in fabrication or design, have led a number of firms to consider inertia welding as an alternate method.
Cost must be considered in any process decision. Frequently, your present process may be satisfactory but inertia welding could make it far more efficient, at considerably lower costs.

"We never could convince ourselves, even with electron beam welding, that we could get a good bond," Mr. Jahnke said. "Inertia welding has changed our minds. It makes fusion welding archaic." — Metalworking News, 1969
"Dauntless efforts on the part of each Interface Welding employee have provided Beech with a means to weld critical, leak-free lines into pressure vessels." — Beechcraft
"Inertia-friction welding of a part for a rocket fuel monitor makes welds that are free of porosity. That's a big improvement over results with gas-tungsten-art and electron-beam welding." — Scholer Bangs, Welding Design & Fabrication
