Structural Welding and Fabrication

High-quality, custom-fabricated engineered replacement parts, fixtures, and tooling

J.R. Smith Welding Service, Inc. provides high-quality, custom-fabricated engineered replacement parts, fixtures, and tooling to support complex repair and modification projects. We specialize in producing obsolete or hard-to-find components, custom designs, modifications, and sub-assemblies for a wide range of industrial applications.

Our capabilities cover everything from heavy plate, structural members, and large welded assemblies to small, lightweight sheet metal and tubing projects. Many of these are crafted entirely by hand in the field—without reliance on computer-automated machinery or stationary shop equipment—demonstrating the skill and adaptability of our team.

We maintain full material traceability, supplying lot numbers for every project, and prioritize domestically sourced, Made-in-USA materials and consumables whenever possible. For foreign-manufactured machinery, we can source original equipment materials directly from European suppliers in metric dimension and thickness sizes to meet exact manufacturer specifications.

We proudly serve industries across Pennsylvania, New Jersey, New York, Delaware, and Maryland, with the ability to travel further when specialized, certified repair solutions are needed.
