It looks to me like this thick shaft was first crudely cut with a welding torch then used as a test bed where some amateur was perhaps taught how to weld. The cut is not too messy but the remnants of the surface welds spell b-e-g-i-n-n-e-r to me.
Since a few weeks, i'm in training for welding & pipefitter.
During free time, i try to build some small weldind art.
Here's my first one still not finish but funny to create it !
i think the first thing i tried to do was not use a flash - i figured the light from the welding arch would be bright enough i could light the subject and be able to knock out the background due to the exposure. needless to say, it didnt seem to work.
I then opened it up and then had a super busy background and a blown out subject.
so i realized i was going to have to use a flash to get this right. so i stopped it down and slowed the shutter to get the amount of streaks that i liked.
i tried a little motion with my camera to see if i could get a really crazy scene and then freeze the subject with the flash. it didnt seem to be working so i didnt push it too much.
so i got an exposure i liked, which is the one on the far right. so then it was just a matter of timing to get the sparks how i liked them. needless to see, the very next exposure was "the one"

With this Tiger (Chinese) laser diode (325nm/~180mw) in a reused driver+enclosure I can fuse/solder the really really fine 40ga cathode wires used in 2.5mm El-wire...
but to be honest I find that the "soldering iron and copper foil" technique is much easier and safer.
I recently tested a 640nm (red) / 205mw diode in this same enclosure and it (regrettably) only lived about 30 seconds before it overheated. Not unexpected, but fun while it lasted - it would burn holes in car tires 5M away.
4 beads, 4 students, 3 have never tig welded before tonight and the other maybe 3 hours. I do enjoy this. My 1st #welding with #tig didn't look like that the VERY 1st time I added wire the puddle. Much to learn and a great deal of room for improvement but an excellent start. The 4 overlapping beads were done by me while demostrating.
