It's hard for me to tell, but I hope you didn't weld a hardened part. You probably already know this, but that is a sure path to failure. I learned the hard way that a weld, or even a nick from a grinder, creates a stress riser that leads to a really fast fail. I was shocked to see how fast a modified 1" shaft would break, while a virgin one would last almost forever.
yeah, heat induced hardening can make parts brittle. unfortunately i don't have much control over some of the materials i'm welding but given that this is a forged driveshaft yoke intended to be welded, it's probably OK. i just did not weld it enough, no biggie.
unfortunately i will destroy the u-joint seals by welding it now, but this only needs to last a little bit and won't have time to rust apart.
