I never understood the concept of welding steel to cast iron. Welding iron is...difficult.
Brazing or silver-soldering makes more sense to me.

The original ball size is 5/8". There is discussion that it is very easy for a small piece of trash to get hung up on the seat and ball since there is not much room for flow. the smaller ball allows for flow and if a small piece of trash makes it through somehow it will not hold open the pressure relief ball causing a drop in oil pressure. I was taught that a .060 washer behind the ball makes up for the smaller ball.
Your are right. for me, I just hit it with the mig and it makes a small goober. never had an issue either way. It's not under any tension/stress, the idea is for it to not fall out. with vibration.
