7018 welds are very strong and tough - often get general bending of
the metal around the weld in overstress - protecting the weld. Even
when ground-at a lot, reasonable penetration can leave hidden bits of
weld remaining, so it can be very hard to break off "temporary
attachments" someone has seen fit to do with a 7018 (where 6013
temporary attachment would serve well but is easily removed).

Yep, 7018 s very ductile and can bend a lot before breaking. This is
why I use it for those "anvil tables" and such.

Please - I am also interested in Iggy's question - relatively, how
does good ER70 rate alongside 7018?

My criterion would be if it HAS to hold, or is subject to a lot of
stress, I'd stick it. Yes, you can crank up the amps on a wirefeed, but
I just feel more confident with a hot 7018, or even 7014 vs. E70.
