Solid-State Spot Friction Welding Systems

Our SpotMeld™ system is a Refill Friction Stir Spot Weld (RFSSW) solution for aluminum and magnesium that provides an alternative to single-point joining processes like resistance spot welding, laser welding and riveting. SpotMeld is an easier process to fixture and its automated tool change capability saves significant time as compared to self-piercing rivet changeover. Additionally, a variety of weld recipes can be used on demand by the robot controller, which results in a very flexible production system. Coldwater Machine Company’s robot mounted SpotMeld head can be integrated with a variety of robots, such as Yaskawa Motoman, Fanuc, Kuka, ABB and others.


  • Joins aluminum, magnesium, non-ferrous and dissimilar materials
  • Flexible sheet thickness in one operation
  • Weld near original material strength
  • High energy efficiency
  • No consumables

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.
