Keep a laminated positions chart in your toolbox. When in doubt, match your joint configuration, welding rod, and technique to the correct cell on the chart.
The pipe is horizontal and fixed (cannot be turned). The Challenge: The welder must weld around the entire circumference. This requires the welder to transition from Overhead (4) at the bottom, to Vertical (3) on the sides, to Flat (1) at the top—all in one continuous bead. It tests a welder's ability to master multiple positions at once.
Identical to 6G, but with a restriction ring placed near the weld joint to limit access. This simulates tight spaces in refineries or nuclear plants. It is widely considered the hardest welding test to pass. weld positions chart
The weld axis is horizontal. In 2G, gravity pulls the puddle down, so you must use a faster travel speed or tighter arc. Vertical
These are the foundational positions found on most certification tests and structural welding charts. Keep a laminated positions chart in your toolbox
While the positions (Flat, Horizontal, Vertical, Overhead) remain the same, the designation changes based on the joint type.
Whether you’re prepping for a certification test (like AWS D1.1) or troubleshooting a tricky job, understanding the is non-negotiable. The Challenge: The welder must weld around the
The weld is performed on a vertical surface (for plate) or a vertical pipe.
The system is simple once you break it down:
