explaining rods

[BrokenBiker]

right, didn't knw where this should fit so ive put it here.

what do the numbers (6013 or 7018 for instance) mean on a welding electrode, or similarly on mig wire like er70s2 (think I may have just made that up for an example)

First numbers are the tensile strength and the rest are the coating and positions it can be used in.

thanks, I had a feeling the 1 meant all positional but wasn't sure, apart from that I was clueless

For ER70S-2 the ER is Electrode/rod meaning it can me used for mig and tig, the 70 is 70,000 psi tensile strength, the S means solid wire and the 2 (or 3 or 6) is the amount of de-oxidisers in it. Hope it helps

cheers. Helped a lot. I mainly wanted to know about the stick welding rods but the mig has always confused me too
