Does the heat generated by welding damage the internal grating? How is it controlled?
Unprotected gratings can be damaged by the heat generated during welding. However, specialized OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor are specifically designed to withstand welding processes and high-temperature environments.
The control mechanism involves the use of robust metal packaging, such as seamless alloy tubes. This packaging acts as a protective barrier, shielding the internal Fiber Bragg Grating (FBG) from the direct heat of welding and the harsh conditions of high temperatures. This design ensures the FBG’s integrity and stable performance even when installed via welding.
