The title says it all.
I know there's a practice of leaving a breather hole at the lowest part of a welded structural tubing for venting out moisture. What I wanting to know is which is the better from a longevity point of view. Welding a structural tubing with a vent hole, or welding it with no vent hole and pressure testing?
The tubing in in this question is 6x6x.25 square tubing, 12' long sections vertical mount to cement pad. The interior of the tubing will not be coated, just paint on the outside with all season weather contact. These are exposed beams.
Thanks all.
