Rooted in invention.
Built to go further, generation after generation.
What started in a garage is now a global manufacturing leader in natural gas sampling, odorization, and instrument-grade gas conditioning — still driven by the same restlessness to make things better.
From one man's garage to a world-class manufacturer.
Robert H. Welker founded the company as a one-man operation, inventing and building devices to solve real problems for the oil and gas industry. That instinct — build the thing that doesn't exist yet, then build it better — never left the company.
Decades later, Welker is a manufacturing leader with a global team, still designing, machining, and testing under one roof in Sugar Land, Texas, and still adding new patents every year.
Every product that leaves our facility is built to a documented, audited standard — not just to spec, but to a standard we hold ourselves to.
Three generations. One standard.

Build Something Greater.
It's not a slogan on a wall. It's the standard behind every part we machine, every system we design, and every relationship we build — a better product, a better system, a better process, a better partnership.
We aren't the type of company to rest on our laurels.
In our 70-year history, Welkerites have designed and patented 90+ solutions for the oil, gas, and petrochemical industries — including the IRA Automatic Insertion Probe Regulator, the WelkerScope® pipeline inspection tool, the ECOsystem™ odorization system, and the inFlow™ ACE Crude Oil Sampler. We keep adding to that list every year.
