Non-contact Temperature Measurement of Stainless Steel in a TIG Welding Process
The goal of this research was to design and test an experimental setup capable of performing a TIG welding process and acquiring temperature measurements near the weld with the use of an infrared spot sensor. The data collected can then be used to validate a computer simulation that models the exact...
