MANUFACTURING SOLUTIONS FOR FORMING, ASSEMBLY AND JOINING
Coldwater is on the forefront of spot welding solutions for lightweight and dissimilar sheet materials. Its SPOTMeldTM Refill Friction Stir Spot Weld system enables spot welding of aluminum (1000 – 7000 series), magnesium, non-ferrous and dissimilar sheet materials. This technology uses rotational friction to heat the materials along with pressure to forge together the parts using wear-resistant tooling to join two or more
surfaces. Heat is generated between the tool and material, creating a soft region. Pressure is then applied, resulting in a solid state joint.
Customers can employ Coldwater to run prototype and feasibility tests at the Solid State Joining Center or have a SPOTMeld system built to specification for use on their production floor.
