Corrosion repair welding

We don’t patch. We replace, weld, and make it last.

Arizona’s heat, water chemistry, and soil conditions don’t take long to expose weak spots in pipe. When corrosion shows up, Earthquake Welding provides certified corrosion repair welding across Phoenix, Tucson, Yuma, and the rest of the state.

We cut out and replace damaged, thinned, or pitted sections on fuel lines, natural gas systems, utility mains, and mechanical piping. Whether it’s a hot spot on a petroleum line or rusted-out steel inside a vault, our welders come ready to remove the bad and replace it with pressure-rated, inspection-ready welds.

Repairs are done to spec—API 1104, ASME B31.3/31.8, or specific utility standards. We also install anodes and CP connections to help extend the life of the repair and the rest of the system.
