BondStir T128

Temperature Data Collection for Friction Stir Welding

Home // FSW Machines & Equipment // BondStir, Temperature Data Collection for FSW


The BondStir is a family of temperature transmitting systems that mount to most standard 50-taper spindles. Replacing the T50 in our standard line of product offerings, the T128 puts no limitation on the welding tool holder – you can use whatever tool holder you already have on hand. The T128 simply takes input from any K-type thermocouple with a standard mini-plug and transmits the data to a remote base station. Data from the base station can be monitored or logged in real-time. When used on a Bond welding system, the T128 can also be used for closed-loop control of the welding tool temperature.

Note: The BondStir T128 requires the use of a thermocouple-equipped welding tool, sold separately.
