6.3 Applications for Temperature Indicators<br />
Temperature indicators can be used for preheat temperature tests and in<br />
annealing and stress relieving procedures, hardfacing, overlaying for<br />
corrosion resistance, flame cutting, flame conditioning, heat treating, pipe<br />
bending, shearing of bar steel, straightening hardened parts, shrink fitting,<br />
brazing, soldering and nonferrous fabrication. The indicators can help find hot<br />
spots in insulation and engines, help monitor temperatures in curing and<br />
bonding operations and help check pyrometric calibration.<br />
