Cold Metal Transfer (CMT) Welding Protection Gas Visualized - CAVILUX Lasers and Schlieren Imaging

Last week we showed you what GMAW looks like with our CAVILUX lasers, today we get to be mesmerized again but in a Schlieren setup of a CMT (Cold Metal Transfer) footage taken at Laser Application Laboratory (LAL) of Tampere University. The video was recorded at 12,000 fps and the protection gas used was Argon 68, Helium 30, CO2 2. In this test our focus was the protection gas flows which is visible in the beginning flowing from the nozzle of the welding torch before being covered by a thick layer of hot air as the result of the process. Pay attention to the moment at the first arc and how the hot air quickly expands like a mushroom cloud covering the protection gas. Protection gas in welding processes can be visualized with careful #Schlieren adjustment and testing preparation. Our ready made Schlieren system provides you with a much easier solution than what you would normally have to go through and saves you hundreds of hours of fine tuning and adjusting that you can spend making new discoveries and contributing to the scientific community.
