Rotary Friction (Spin) Welding Systems

Our SpinMeld™ friction spin welding systems can join steels, aluminum, cast or sintered metals, carbide materials, magnesium, nickel, molybdenum, and other exotic materials that normally may not be welded using other methods. The SpinMeld process is servo controlled with a high-speed spindle bringing critical parameters under control with in-process monitoring to improve part quality and eliminate post weld inspection.

Will It Meld?

SpinMeld can lower the cost to manufacture a wide range of applications where a high strength, non-porous joint is needed. Because the process is very fast, with weld times typically under 3 seconds, it is often possible to replace other processes including arc, resistance and projection welding with better results. The chief advantage of SpinMeld is the ability to produce a superior joint on a wide variety of materials without altering the crystalline structure of the base materials and so the joint strength is very high and the heat affect zone small.

SpinMeld Applications

Available SpinMeld Solutions

SpinMeld systems are available with automatic parts handling and inspection, as stand-alone units or may be integrated into a turnkey solution. Each machine is designed to fit the individual application with parameters such as rotational speed, cycle time, and forging force fully customizable.

SpinMeld is appropriate for high volume environments where at least one of the components is cylindrical in nature. At the Lincoln Electric Automation Coldwater facility, our efforts are focused on smaller part sizes, as indicated below:

For Smaller Parts

  • Components that are round, hex or symmetric shape such as standard nut, flange nut, stud or flange stud, a boss
  • Thickness of at least 0.100-in and as long as 4.0 – 5.0-in. stud
  • A diameter size of 1.50-in. or smaller for solid pieces or up to 2.0-in. for hollow tubes
  • Average part to part cycle times of about 7 seconds, but it can be less depending upon the component
  • Maximum weld area of 1.77 in2 (1140 mm2)

For Bigger Parts

Please contact us to discuss your specific requirements.


  • Consistent weld duplication
  • Dissimilar material welding
  • Significantly faster weld times (usually < 3 seconds)
  • Forge-strength welds
  • Leak-proof joints
  • Non-corrosive bonding
  • No flux, filler or other consumables
  • High energy efficiency
  • Environmentally friendly
  • Process monitoring of weld parameters for statistical process control

Prototype Project Requests

We accept applications for prototype project requests. Please submit your initial request for parts joining prototype work. We can work to produce custom parts that make use of advanced joining technology as well as apply a joining to your existing parts. Provide some of the information below and we’ll contact you for more details and state the process with your team.
