Discover the intelligent and cost-efficient approach to producing those “impossible” welds

OUR JOINING TECHNOLOGY

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”.

OUR SPECIALITY
Expand and extend your product line with bimetal components

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.

Common Industry Solutions

Product application areas vary from aerospace and aircraft, both military and reactors, hydraulics, valves, automotive racing and family cars, oil field drilling and production, cutting tools, turbines, gears, shafts, and many others that are critical and exciting.
How we can help in your manufacturing process

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.

PRODUCT IMPROVEMENT


Problems in fabrication or design, have led a number of firms to consider inertia welding as an alternate method.

COST
REDUCTION


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.

Inertia Welding Advantages

High weld integrity

It is a solid state process that does not suffer from inclusions and gas porosity

Cost reduction

Replaces costly forging castings

Excellent repeatability

Process is controlled by machine so results are highly repeatable

Bonds dissimilar metals

Dissimilar metals can be joined with no alloying of the metals

Joint strength

Bond strength is comparable or greater than parent material 

TESTIMONIALS

  • "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."
