What is a 6G Weld Test?
The 6G weld test is considered the toughest and most comprehensive welding qualification. Unlike flat or rotated tests, it requires welding a pipe positioned at a 45-degree angle, simulating real-world conditions with restricted access and gravity challenges. Welders who pass demonstrate readiness for both shop and site work, resulting in fewer repairs, stronger joints, and higher quality welds. Adopting the 6G test as a standard can help businesses build stronger teams and achieve better results.
- Not all welds are equal; site conditions make welding challenging.
- The 6G weld test involves welding a pipe at a 45° angle.
- Welding positions:
- Uphill: from 6:00 to 12:00.
- Downhill: from 12:00 to 6:00.
- Recognised as the toughest welding test.
- Passing proves both shop and site readiness.
- Benefits: fewer repairs, stronger joints, higher quality welds.
- Recommended as the standard for training and testing teams.
