Welding certification is a test of work experience and qualification of welders. The certification is conducted by an authorized certified welder inspector.
Types of Certifications and Positions
Certified Welder – Groove and fillet welds in flat, horizontal, vertical, and overhead positions with unlimited thicknesses and 3G and 4G certifications.
The main welding certifications are:
- Certified Welder (CW)
- Certified Welding Inspector (CWI)
- Certified Welding Educator (CWE)
- Certified Resistance Welding Technician (CRWT)
A Level 4 welder has advanced expertise in Gas Tungsten Arc Welding (GTAW). Welding in a 3G position means moving the torch vertically, up and down.
Welding Ranks and Levels
What are the ranks in welding? The highest rank is the Certified Welding Inspector (CWI) certification. CWIs ensure welding operations meet standards by inspecting procedures, materials, and personnel.
The highest level for a welder is 6G, meaning they can weld 360 degrees around a pipe. A number/letter shorthand identifies different levels of proficiency. For example, "4-G" means groove welding.
