Friction Welding Systems

In Booth S-2158, Coldwater Machine Company (Coldwater, OH) will promote its SpinMeldTM friction spin welding system. SpinMeld technology can join steels, aluminum, cast or sintered metals, magnesium, brass, carbon fiber composites, ceramics with mixed metal connections, and dissimilar combinations of these materials, as well as reducing cycle time and defects when compared to traditional welding or joining techniques.

SpinMeld systems are available as stand-alone vertical or horizontal machines that can be integrated into a work cell or an automated processing line. Each system is designed to fit the individual application with machine parameters such as rotational speeds, cycle times, and forging forces based on the material composition, part configuration and contact surface area of each joint. Rotational speeds are available from 2,000 rpm to 23,000 rpm and forging forces from 335 ft-lb to 12,000 ft-lb.

The systems can be designed with a maximum weld area of 0.992 in2 (640 mm2). SpinMeld systems rely on rotational friction welding principles and a direct drive approach, where a spinning workpiece, driven at a constant speed by an electric motor, is joined to a stationary one by rotational friction and externally applied force. This is an environmentally friendly process that eliminates the need for filler metals, fluxes or shielding gases. It also produces higher quality joints with small heat affected areas and consistency in weld duplication.

Coldwater Machine Company is a leader in the design, build and integration of specialized equipment for discrete manufacturing with extensive precision-machining capability primarily serving companies in the automotive, aviation, aerospace, appliance and energy industries that are producing products requiring tight tolerances. With over 50 years of experience, the company’s key competencies include precision machining and assembly, engineering support, design and build of specialized manufacturing equipment, and solid-state welding/joining systems.
