Ensure reliable, consistent attachment of thermocouples for accurate heat treatment monitoring. The TAU90 Thermocouple Attachment Unit is a portable welding device used to securely and reliably attach heat-treatment thermocouples to the metal surface of workpieces. It creates a consistent welded junction that guarantees accurate temperature readings during preheat, stress relief, and post-weld heat treatment (PWHT), which is critical for quality control and compliance.
