3G WELDING
A 3G welding certification demonstrates a welder's ability to weld vertically, which is considered one of the more challenging welding positions. The certification covers:
- Groove and fillet welds
- Flat and horizontal welds
- Vertical groove welding, which involves joining metal plates or sections with a groove joint along a vertical axis
To earn a 3G welding certification, you must pass a 3G weld test, which involves:
- Welding a groove joint using a specified process, such as MIG (Metal Inert Gas), FCAW (Flux-Cored Arc Welding), or SMAW/stick welding (Shielded Metal Arc Welding)
- Having the weld inspected for defects
- Demonstrating proficiency in several areas, including:
- Setting up the welding area
- Adjusting equipment settings
- Cleaning splatter
- Positioning
- Angle
- Electrode consumption rate
- Setting up the welding area
The 3G test covers both 1G and 2G positions. The 1G position has the plate in a beveled flat position, and the 2G position has the plate in a beveled horizontal arrangement.
You can obtain welding certifications from organizations like the American Welding Society (AWS). To maintain your certification, you must submit a Certification Maintenance Form every six months.
