I am getting some drill pipe. Recommended to be welded with 11018 rods to
keep from cracking. I need to weld on some very light purlins, 12-14 ga.
Should I weld a plate on top of the pipe, then MIG the purlin on the plate?
Or do you think I can weld the pipe directly to the purlin welding in the
overhead position if I keep the puddle on the pipe? And if I do, what would
be the chances on cracking.
This is going to be a pole barn. Pole supports. Horizontal purlins,
sheeting on top. Should flex a lot. Should I add cross bracing?
