You cannot "wash" over the metal in 4G. If your arc length varies by 1/16 of an inch, you will have a pile of molten metal on your hood. This position forces you to master:
For new welders, this is the shocker. In flat welding, you see the puddle clearly. In 4G, the puddle is overhead, so you are looking at the bottom of the puddle. You have to weld based on feel and the sound of the arc (a crisp "frying egg" sound) rather than sight. 4g welding position
Note: A 4G certification typically qualifies a welder to weld in the 1G (Flat), 2G (Horizontal), and 4G (Overhead) positions, but the 3G (Vertical) position. You cannot "wash" over the metal in 4G
Welding in the 4G position presents several challenges and considerations: In flat welding, you see the puddle clearly
The 4G welding position is a true test of a welder's skill. It requires a combination of lower heat settings, precise travel speed, and the ability to maintain a steady hand while working in an uncomfortable posture. Mastering 4G proves that a welder has excellent control over the molten puddle and opens the door to high-paying structural and industrial welding jobs.
The "4" in 4G stands for the , while the "G" signifies a groove weld (typically a butt joint between two plates). Unlike its counterpart, the 4F position (overhead fillet weld), 4G requires the welder to penetrate deep into the "V" or "U" shaped groove of a horizontal joint.
