We have a great welder who does not have bones in his hands.

@@burnsstainless2607 😂 seriously I would love to see the cup and tungsten on that guy's setup, boneless or not! Excellent work guys.

​​​​@@burnsstainless2607 I know this is an old comment, but I suspect you'll appreciate the following. I work in nuclear power and our fuel assemblies are comprised of fuel pins that are in the 0.3 to 0.5 inch diameter range. These are about 12-14 feet long and there are as few as 14 x 14 and as many as 17 x 17 pins in an assembly. Along their length are a number of spacer grids which help keep the pins straight, but also help introduce mixing in the water flow. These spacers are made of stamped sheet metal and fit together with interlocking slots. They are then welded together into a single piece. Today, this is done with automated laser welding and it's nearly impossible to even see the weld. However, it used to be done by a "team of grannies," who were the only humans available with small enough hands and fine enough motor skills to do the job. Memory tells me they used to be brazed, but I'm not sure how well that would take the temperatures and (especially) irradiation those would see (frankly, I don't know much about brazing). Regardless, I always found it humorous to think that the entire nuclear fleet's operation was beholden to these old ladies!
