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.
Coldwater Machine is a leader in the development and manufacture of solid-state welding solutions that specifically address lightweight, we have deep experience with traditional MIG and resistance welding technologies that is a greatly expanded capability with access to the global resources of the Lincoln Electric Company. We have designed and produced automated weld cells using fiber lasers, CO2 lasers, MIG (GMAW) and friction solutions.
Our Solid-State Joining Center is focused on furthering the development of processes that enable the joining of materials at temperatures below their melting point and without the addition of filler metal or shielding gases. We are partners with the Edison Welding Institute, LIFT (Lightweight Innovations for Tomorrow), as well as other research institutions helping to commercialize new joining technologies for the production environment.
The Solid-State Joining Center also houses a Materials Evaluation and Testing (MET) lab that provides microstructural evaluation in addition to mechanical testing for weld tensile and hardness verification. This on-site service provides prompt verification of weld integrity, enabling Coldwater Machine to shorten the development time for laser, solid state and arc welding customers.
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.
