About Us
A&G Welding Specialty LLC is an ISO 9001:2015 certified welding and fabrication contractor headquartered in Houston, Texas. We provide turn-key welding, Inconel cladding, precision machining, pressure fabrication, and Post Weld Heat Treatment (PWHT) — all under one roof — for the oil & gas, power generation, and industrial sectors.
Founded on a commitment to code-compliant quality and zero-compromise craftsmanship, A&G has built its reputation on delivering critical welds, Inconel 625 overlay on 4130 chrome-moly, fracking valve & spool repair, and complex fabrications that meet ASME Section IX, API 6A/16A/17D, and NACE MR0175 standards. Our on-site PWHT capability — a service most shops subcontract out — means faster turnaround and full documentation control from start to finish. Our Houston shop serves customers throughout Texas and the Gulf Coast, upstream, midstream, and downstream.
Mission Statement
Our mission is to deliver precision welding and fabrication services that oil & gas operators can rely on when it matters most — during turnarounds, critical repairs, and demanding new construction projects.
We hold ourselves to the highest standards of quality, safety, and integrity on every job, large or small. Every weld we make is backed by certified procedures, qualified welders, and complete documentation — so our customers can move forward with confidence.
At A&G Welding Specialty LLC, we measure our success by our customers’ ability to keep their operations running safely and efficiently.
