Thank you for all the replies to the question.
Another part of it:
What wire type I mean; for stick welding I use 7018 rod for equipment welding it's a strong weld.
I wonder what is the number of MIG wire to use for strong welds that's equivalent to 7018 rod?

Is the wire 70S6 wire equal to 7018 stick rod? Or ?
