Tools of the Trade: To the non-welder, welding is a mysterious process hidden from view by a blinding ball of light. The welder sees more, being close to the action and able to look through the visor. But before the invention of high-speed camera no one saw anything like this—ultra-slow-motion video of what happens when metal is joined by welding.

These are so cool! I have only welded once in real life, and it's super interesting to see what is really going on. I don't know many of the differences between MIG and TIG welding, but it is cool to see the physical differences in these videos. Another piece of information that would be cool to know is how fast a weld occurs based on the type of weld and what you are welding. Other than that, these videos are super enjoyable to watch.
The last video, the one by the Canadian Center for Welding and Joining is the eeriest for me. I understand that because of the extremely high frame rate that the globule only appears to be falling slower, and that it doesnt actually levitate like that, but its still cool. I like how the globule is interacting with the magnetic field produced by the welding current, and causes it to move like it does. The article said there was no useful reason to watch the videos, I disagree. It hadn't crossed my mind before that the reason that welding sparks is that the metal is boiling quickly and causes a small pressure explosion, very cool.
Freaked me out how much the metal just looked like water. It was just like you wanted to put your finger into and push it around. Like it would be FUN. It was really kool just seeing the metal just metal together in a nice little pool.
It would have been great to have that technology when I was learning to weld. Ben could have been like, “you are screwing up right… Now”. Kind of like when you video take a golf swing for practice.
Also I was thinking about how it would have been great to have some music behind the music. Thinking a lot about classical music, coming off the article about the dyeing orchestras around the country. It is amazing just a little bit of music could have made those video viral, but just sitting there with nothing makes them boring and hard to watch, at least for me.
Those videos looked really cool and artsy, and it would be interesting to see what they would look like with different color filters over them. I learned how to weld this summer, though it was really just an introduction, and I'm really looking forward to hopefully taking Ben's class next semester. I've wanted to learn how to weld for a while now, and I think that it's such a cool process. Seeing these videos only made me want to learn it more. I liked what Adam said about using a camera to record yourself welding to see what mistakes are being made, and I think that something like that could be really effective. I also think it's so cool how liquid-like the metal becomes, and how in the slowmo videos it looks like water. It was also really cool to see the puffs of gas in one of the videos. I would have liked to hear what was going on as well. because I think that the slowed sound would also be really cool to listen to.
These videos are really cool, and I havent ever seen anything like them. I am somewhat amazed at just the artistic beauty of what the welding looks like. It looks like puddles of water being carefully and artistically lit. I also think these videos could be extremely useful in terms of teaching someone how to weld for the first time or explaining the welding process. I thought the MIG one was particularly interesting due to not just the speed at which the video had to be taken, but also the closeness. The wire that to us looks like a wire, in the video looks like a solid rod of material.
I don't know a whole lot about welding, but it's something I'd be interested in learning how to do in the future. Watching these videos was really cool because I got to see what happens when you weld, but at a slower, closer, and less bright way. It's neat how the beads of metal pile together as a continuous piece. I really liked the first one because you say how it completely went right over the other grooves and made its own. It was such a different perspective from the others that it was cool to see how it looked when it moved away from the bead it had just made.
