A world leader in friction welding, MTI provides one of the largest selections of inertia welding machines. Due to the quality of inertia forge joints, the applications are almost unlimited and MTI uses this method for welding aircraft components, hazardous material containers and even space components.

Advantages & Benefits
Any shape, strong joint
Inertia welding allows for any configuration of weld interfaces – any combination of bars, tubes, discs or plates can be joined. The inertia method consistently produces quality strong joints of complex components that would be either difficult or costly to create otherwise.
Smallest heat affected zones within rotational friction welding methods
Due to a smaller surface area of parent material being affected by heat in the joint area – the material properties are retained, leading to stronger efficient welds.
Money and time savings due to reduced welding time
Reduction in weld cycle time leads to an increase in the volume of parts that can be welded in the same time. An example of submerged arc welding, a large diameter cylinder rod may take 20 minutes whilst the same joint using the inertia welding method would take less than five minutes.
Spiral weld leads to increased strength
Due to the use of a flywheel, the weld flux has a spiral pattern at the weld joint. The spiral/helical joint causes an increase in the weld strength.
Two parameters of RPM and pressure to control
Because only the RPM and pressure parameters are controlled, the inertia method is not only uniformly consistent but importantly, not reliant on the operator’s skill level. Inertia has the fewest control parameters, leading to increased quality control, reduced monitoring and easier troubleshooting, resulting in time and cost savings.
Mathematical scalability via pre-calculable parameters
Because of mathematical relationships of energy, load and weld area scale modelling can be used to reduce cost, risk and time. The world’s first 2,000 tonne inertia friction welder produced by MTI, demonstrated this by building scaled components on a 450 tonne machine – saving the client’s time and risk thus reducing investment costs.
