Flame Hardening

Flame hardening involves the direct application of a flame to the metal, which hardens the surface without affecting the substrate material. Temperature monitoring is vital to control the level of surface hardening without affecting the entire metal part.

Traditional contact devices measure the flame, not the part, so non-contact methods are essential, by using a 3.9µm wavelength the pyrometer or imager “sees” through the flame and measures the hot metal surface. 

AMETEK Land’s measurement solutions operate with a waveband that sees through the flame to measure the true surface temperature of the metal. This enables precise quality control to ensure surface hardening is properly achieved without affecting the internal properties of the metal part.
