Yes - vents into the shop area (!)
My uncle works for NASA and was telling me about a laser that they considered purchasing. Apparently it had a cat walk (if that helps you imagine the size) and the beam was apparently a foot wide. According to him… That was the “small laser”
I heard that the new heavy lift vessel they are going to be building uses a new method of welding maybe this is it
Back in 2002 I did some server work at a laser shop and the production floor was over head gantry feeding machines was so massive and out side dozens of ln2 tanks 5 floors tall
