Client Testimonials

We've worked with Weldstar for many years and they continue to provide quality materials with no certification problems, which is very important at a Nuclear plant. Their sales reps will do whatever is required and have gone the extra mile when called upon.

- David L. Diederich, Exelon Nuclear


As the Corporate Welding Manager for Exelon I had many opportunities to work with Weldstar regarding filler metal procurement. I found them to be very responsive to resolving issues identified by Exelon. This included working closely with Exelon to resolve shipping issues identified during receiving, and expediting emergent additional testing required to support station welding requirements. I always felt comfortable communicating with Weldstar management and support personnel knowing they would work in our best interest to support our needs.
