[TheForge] RE: Welding

How have I've maligned 7018? 

I wasn't speaking of accomplished welders. An accomplished welder doesn't cold 
lap a weld, or overamp, undercut, etc. either.

Sure the beginner can cold lap a weld with other rods but I've found mig to be 
the worst with 7018 maybe second or third for poor welds that look good. It's 
not the rod's fault poor or inexperienced welders misuse it. As for singling 
out 7018 I suppose it is unfair but I haven't used all that many different 
rods. 

Now that I think of it the knotheads I used to work with insisted on using 
Super Missle weld on everything till I finally hid it. In just what universe 
does someone need 140,000psi SS rod on mild steel?

Anyway, 7018 is my hands down personal favorite rod. I've burned more of it 
than all the other rods put together except perhaps Lincore-50 hardfacing wire.

Heck, rereading my statement AGAIN just now, I frankly mispoke.
I reread my post several times before sending, I almost always do and still I 
miss things this wrong. They CAN make poor welds if misused. Not will. CAN.

Regardless, I think we're on the same page Bill, I just didn't express myself 
very well. I'm glad you spoke up, I really don't want to go in the records 
this far off the mark.

Thanks

Frosty
