About US

At Earthquake Welding, we’re built for the heavy-duty work that keeps Arizona running. Based in Phoenix and rooted in the Valley, we’ve spent over 20 years welding the pipelines, petroleum systems, and industrial piping that power, fuel, and connect this state.

We bring certified, code-compliant welds to every job—whether it’s a high-pressure gas line, a terminal upgrade, or a mechanical piping project. Our team is hands-on, accountable, and committed to getting it done right the first time, because critical infrastructure doesn’t get second chances.

When safety, schedule, and quality matter, we’re the team Arizona contractors and operators trust.
