I found this weeks class very interesting. One thing I liked in particular was the different types of welding. I honestly only knew about arc welding, I didn't even know gas welding was a thing. Additionally, when I think of welding I think of something super complicated only highly trained professionals can do for super complex projects but, after seeing how it actually looks and doing some research on my own, I realized it can be used for various projects not just large industrial ones. Lastly, It was cool that I got my question from a few lesson ago (I think week 7) about why different metals will change when exposed to different voltages.
