Hydrogen Diffusing from Weld Metal

This is a video of a neat experiment that I do with students to show how important it is that low-hydrogen electrodes be stored and used correctly. The experiment is super simple and works for me each time. The longer the E7018 is left out of the oven, the better the result but I generally leave it out only 24 hours. The E6010 is the most impressive.
