Beading on ejector tip - what rod?

[Ryan in SD]

I recently did some surgery on 2 of my guns AK pattern guns. I think the rod I used was equivelent to mild steel. I am not a welder but I use a tig in the shop on minor things here and there.

My question is. Will the average filler rod be strong enough for an ejector tip?
Should I redo it and get some 4140 rod and grind off the old tip?

I use ER70s2 for most stuff on the TIG. The key is the heat you put into the ejector, that weld deposit is heat treated and should be GTG as is.
