Yes, that 7018, if it is there, it will hold.

Bit late to the party (thread) here. I will add that i don't use MIG
where high forces are involved. its just too easy to have a nice
lookin' weld with poor penetration using MIG.



I feel exactly the same. If I have a 7018 weld, and it looks half
decent, I am completely assured that it will hold as well as anything.

In a situation where all welds are x-rayed I'll fully trust a wirefeed
weld. In robot welded structures, I'll pretty well trust a wirefeed
weld.
If I know for sure that a welder is an excellent welder, I'll trust a
wirefeed weld if he can show me a test cupon of the same type of weld
with proper penetration.
