So I laser weld, and beyond my own PPE, interlocks (gun won't fire if it's not touching metal, etc), the most important part of the whole setup is laser safety curtains.
Because it's a 2500 watt laser, if i didn't have laser safety curtains , the relections/etc could very easily blind someone at a fairly long distance.
The NOHD (nominal ocular hazard distance) is something like 10km (2500 watt laser, 0.06mm spot size, divergence is very very small). The actual hazard distance is shorter, but still, kinda crazy.
(as for why i have a laser welder - i got it cheap and besides the downsides above, it is very easy to weld ~anything without much skill. A person who has never welded in their life can weld sheet metal and have it come out basically perfect in 5 minutes)
