Construction Industry

Our role in the Construction Industry.

We perform weldability evaluations by performing chemical analysis to determine the composition of the material and tensile testing to determine the mechanical properties.

Using the data from these tests we can determine the carbon equivalency, weldability, and recommend the proper welding rod for the application — critical for structural steel, infrastructure work, and cold-weather Charpy-impact-qualified builds.
