Cold Metal Transfer or CMT is a welding process developed by Fronius of Austria. While the name implies the process being “cold”, reality is that CMT generates so much brightness and heat that it is very difficult, if not impossible to see what goes on beneath the bright light. However, using the Cavitar Ltd. Laser Illumination, researchers at LABSOLDA Institute of Welding and Mechatronics in Brazil have managed to capture this amazing footage. With the brightness of the arc reduced, the footage
