Pipe Welding & Structural Fabrication in Raleigh, NC | 6G Certified
Industrial-grade structural fabrication and pipe welding. When the weld absolutely cannot fail, you need Raleigh's 6G certified expert.
The 6G Certification Difference
In the welding industry, 6G is the gold standard. It requires the welder to join pipes at a fixed 45-degree angle without rotating the pipe. This means the welder must execute perfect welds in overhead, vertical, and horizontal positions simultaneously. Most fabricators never achieve this certification. When Chris Roberts handles your structural pipe welding or heavy fabrication, you are getting a level of skill and integrity that is rare in the residential and commercial sectors.

Inspection & Finishing
We clean the welds, inspect for complete penetration, and apply protective coatings as required.

Uncompromising Structural Integrity
We don't just build things to look good; we build them to withstand the test of time. Every weld, every joint, and every anchor point is engineered with precision and care. As a 6G position certified welder, Chris can weld pipe in any orientation — horizontal, vertical, overhead, and inclined.
- Full-penetration groove welds on structural connections
- SMAW (stick), GMAW (MIG), and GTAW (TIG) processes all available depending on material and application
- Weld inspection available via visual and dye penetrant testing
- All structural work meets AWS D1.1 structural welding code
