Horizontal Position In Welding [best] <1080p>

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

Marco was a second-year welding apprentice working on a water treatment plant upgrade. His task: weld a support bracket onto a 12-inch horizontal steel pipe that carried non-potable water. The pipe was stationary, about chest-high, and the weld was a simple fillet—a perfect opportunity to practice. horizontal position in welding

“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.’” Marco shrugged

His journeyman, Lou, was a quiet veteran with 30 years of experience. Lou looked at Marco’s setup and asked, “What position are you using?” Marco was a second-year welding apprentice working on

The lesson Marco never forgot: Welding on top of a horizontal pipe is horizontal position welding (per AWS: 2F for fillet, 2G for groove)—and it requires deliberate technique to manage gravity’s sideways pull. Ignore that, and your weld will sag, undercut, or fail when it matters most. Takeaway for your own work: When you see a horizontal joint (the weld’s length runs left-to-right), always remember—gravity is not your friend. Aim slightly upward, keep a tight arc, and watch the puddle’s lower edge like a hawk. That small adjustment separates a pretty weld from a safe weld.

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