About Us

WELKER > About Us

Our Story

Rooted in Innovation

When Robert H. Welker started the company out of his garage, Welker was a one-man operation dedicated to inventing and manufacturing devices to improve the oil and gas industry. Sixty-five years later, Welker is a manufacturing leader with over 100 employees who are committed to creative quality solutions.

Branching Out
Not content with the status quo, the company has carried the legacy of inventiveness and advancement into the third generation. Under the leadership of Brian Welker, the company gained momentum, developing and patenting new products every year, and his background in machining helped Welker evolve into the world-class manufacturing company it is today.

With our extensive industry and product knowledge and the know-how of experienced employees, Welker is perfectly positioned to be your one-stop-shop for turnkey solutions for the oil and gas industry and beyond.
