Linear Friction Welding

Able to join a nearly limitless number of shapes and complex part geometries, Linear Friction Welding joints are of forged quality, with a 100-percent butt joint weld through the contact area. Linear Friction Welding can join dissimilar metals incompatible with conventional welding methods. This allows engineers to design bimetallic parts and near-net shape parts that use expensive materials only where needed.

Using Linear Friction Welding to join near net shape parts with geometries designed to use expensive material only where needed provides a faster, much less expensive alternative to machining parts from solid blocks. The state-of-the-art machine has the largest tooling envelope of any linear friction welder in the world. It’s available now for full-sized part development in Detroit.

From blisks to bumpers, MTI’s LF35-75 is equipped to handle the largest parts in various industries. The state-of-the-art machine has the largest tooling envelope of any linear friction welder in the world. It’s available now for full-sized part development in Detroit.

MTI’s machine-controlled process eliminates human error, making the bond quality completely independent of an operator’s skill level. By reducing the number of defective parts fabricated, your investment of time and materials is put to its best use. Since there is no melting, solidification defects don’t occur in Linear Friction Welding, thus virtually eliminating gas porosity, segregation, or slag inclusions.

The Linear Friction Welding process is at least twice—and up to 100 times—as fast as other welding techniques. Multiple pieces can be bonded simultaneously, helping to reduce cycle time.
