I'm thinking of welding some 4130 steel, I've not welded anything other than mild steel so far. Do I need to do anything differently when welding 4130 compared to mild steel? amps/settings? Also what is the best type of filler rod to use when welding 4130 to 4130. Also is it possible or advisable to weld 4130 to mild steel and if so, what is the best rod to use in this situation and are there any other things I need to be aware of?
Thanks.
Thanks.
