This TIG welding research video was captured using CAVILUX HF laser illumination at 1,000 frames per second. It was produced by Rafael Nunes as part of his Bachelor Thesis on GTAW (Gas Tungsten Arc Welding) automatic processes at LABSOLDA, the Welding and Mechatronics Institute in Brazil. The bright star-like effect in the footage is caused by the laser light reflecting off the spherical surface of the molten filler droplet, acting like a mirror. This technique allows for clear visualization of
