Description
Resistance spot welding is the process used in the automotive industry to assemble body-in-white. A high current allows the melting temperature of steel sheets to be reached by Joule heating in a few milliseconds.
An experimental setup was developed to measure the contact temperature during welding. A high-speed infrared camera equipped with a G1 microscopic lens is used. The measurement is biased by the source size effect.
We propose a method to quantify and correct for this effect and obtain an accurate temperature reading.
