6g Welding Position Definition =link= Here

And when you pull off a perfect 6G weld—uniform cap, no undercut, X-ray clean—you've earned a quiet pride that only other pipe welders understand. The 6G welding position is the definitive test of all-position pipe welding skill. If you see "6G" on a welder's resume, you're looking at someone who can weld anything, anywhere, under any conditions. It’s not just a position—it’s a statement. Next time you see a refinery or a power plant, remember: much of that pipe was welded in 6G, by someone who refused to let gravity win.
