If you’ve ever looked at a welding procedure specification (WPS) or a certification form and seen codes like 1G, 2F, 3G, or 4F , you’ve encountered the welding position chart. Understanding these codes isn’t just for passing a test—it’s essential for producing strong, sound welds and knowing which techniques to use.
Disclaimer: Always follow your specific WPS and safety guidelines. Positions can vary slightly for pipe welding (5G, 6G), but the principles above cover 95% of structural plate work. welding position chart
