TEMPERATURE MEASUREMENT BY UV THERMAL RADIATION
F. Miyasaka, T. Ohji, Y. Fujii
Abstract:
The accurate measurement of temperature is very important to achieve high quality products in materials processing such as arc welding and thermal cutting. The IR(infrared) radiation thermometer has been applied to these processing, because it requires no physical contact with an object. Generally, the radiation thermometry leads to noticeable error in measuring temperature of molten pool under the welding where the emissivity is unknown. In the present paper, the molten pool temperature measurement by UV(ultra violet) thermal radiation has been discussed. In the experiment, stainless steel have been melted with TIG(tungsten inert gas)-arc, and the temperature distribution of molten pool has been measured with an UV sensor system and IR sensor.
