Coldwater Machine Company Announces New SpotMeld System For Spot Welding of Non-Ferrous and Non-Metallic Flat Materials
Coldwater Machine Company has developed a new refill friction stir spot welding (RFSSW) system that can join aluminum, magnesium, non-ferrous and dissimilar sheet materials.
February 10, 2015
Coldwater Machine Company, a leading engineering solutions company that manufactures and integrates precision equipment and tools for multiple industries, has announced its new SpotMeld (TM) system, which is based on Refill Friction Stir Spot Weld (RFSSW) technology. This new solution, available from Coldwaters Solid State Joining Center, enables spot welding of aluminum (1000 - 7000 series), magnesium, non-ferrous and dissimilar sheet materials, offering an alternative to single-point joining processes like resistance spot welding, laser welding and riveting.
"With the move toward lightweighting, OEMs are all looking for the most effective way to cut weight without sacrificing quality or safety," said Tim McCaughey, Coldwater Machine president. "The existing technologies needed to process these lighter material typically add weight or cost, result in low weld strength, or have porosity defects. Our friction spot welding system overcomes these issues and is efficient enough to run in a production environment."
Coldwater Machines SpotMeld friction stir spot welders can be configured to application specifics and mounted on any industrial robot. A variety of weld recipes can be used on demand by the robot controller, which results in a very flexible production system.
Relying on RFSSW technology, the SpotMeld system 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. Basically, heat is generated between the tool and material, creating a soft region. Pressure is then applied, resulting in a solid state joint. In addition to its ability to join dissimilar and lightweight materials, benefits include high quality joints with a small heat affected zone, consistency in weld duplication and faster weld times, as well as being environmentally cleaner and safer with no filler material, spatter, smoke, radiation or shield gasses.

FLIR Si1-LD - Industrial Acoustic Imaging Camera for Compressed Air Leak Detection
The FLIR Si1-LD is an easy-to-use acoustic imaging camera for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed camera is designed to help maintenance, manufacturing, and engineering professionals identify air leaks faster than with traditional methods. Built with a carefully constructed array of MEMS microphones for high sensitivity, the Si1-LD produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital image, allowing you to accurately pinpoint the source of the sound, with onboard analytics which quantify the losses being incurred. The Si1-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Transferring of images can be managed via memory stick or USB data cable. Through a regular maintenance routine, the FLIR Si1-LD can help facilities reduce their environmental impact and save money on utility bills.
