I stopped by a friends shop yesterday and he had a freind of his welding a
.625" plate he was stick welding to the rear of an old international dump
truck. I asked what rod he was using and the one guy said "7031" (it looked
like 3/16" or 1/4" dia.)
Let me know if i have this straight since i do very little stick welding
(all i ever use is 1/8" 6013 rod and it's rare, usually grab the mig) but
the "70" means it's 70,000psi, the "3" is flat position, (which i thought
"1" would be better since he was stitching up in a vertical position) and
the "1" would be ac, dcep or en.
I have never seen 7031 electrodes, could he have meant 7013?
