Expert TIG Welding and Metal Fabrication
RENJOHN offers specialized TIG welding services for high-strength, high-precision metal joins. Whether repairing cracks, reinforcing worn parts, or customizing new builds, our TIG welding services provide structural integrity and durability across ferrous and non-ferrous materials.
Engine and Earthmoving Component Repairs
We work extensively on engine components, cylinder heads, manifolds, chassis, brake systems, hydraulic components, and more. Our machining and welding processes help extend the life of earthmoving and industrial machinery—minimizing downtime and reducing replacement costs.
