Welding Defect - Watch How Porosity Happens!

This video shows welding defect porosity as it is happening in a CMT (Cold Metal Transfer) process. You can see the tiny round formations shooting upwards from the melt pool leading to porosity in the weld. TWI Global says that “Porosity is caused by the absorption of nitrogen, oxygen and hydrogen in the molten weld pool which is then released on solidification to become trapped in the weld metal” (www.twi-global.com). The footage was captured using a high-speed camera at 7.000 frames per second and our CAVILUX laser illumination as the light source. Video was taken in cooperation with the Laser Application Laboratory (LAL) of Tampere University, Finland.
