Horizontal Position In Welding [hot] Link

“Flat, of course,” Marco said, pointing to the top of the pipe. “The bracket goes here.”

Lou knelt beside him. “You fought gravity. In flat position, gravity helps you. In horizontal position, gravity pulls the puddle down . You need to aim your rod slightly upward and pause on the top edge to let the metal freeze before it sags. Also, run a stringer bead—don’t weave wide.” horizontal position in welding

Within three inches, his molten puddle sagged. The top bead looked fine, but the toe on the lower side was jagged—metal had dripped downward before solidifying. He tried speeding up, but that just created cold lap. Frustrated, he chipped off the slag and saw the truth: a weak, uneven weld with undercut along the bottom edge. “Flat, of course,” Marco said, pointing to the

“So the weld’s axis is horizontal,” Lou said. “Even though you’re welding on top, that’s not a flat position weld. That’s horizontal position—because the pipe’s centerline runs side to side. If you weld it like a flat plate, gravity’s going to pull your puddle down the side before you can say ‘undercut.’” In flat position, gravity helps you

Marco shrugged. He’d done flat welds before. He struck an arc.
