What gets welded

Stick, MIG, and flux-core on a fully self-contained mobile rig. If it's steel and it's broken, bent, or needs building — that's the job.

Structural steel

Beams, columns, base plates, moment connections, stairs, rails, and supports — welded in place on commercial and residential sites, to spec.

Heavy equipment repair

Cracked frames, broken mounts, worn pins and bosses on excavators, loaders, screeners, and attachments. Repaired on-site to cut your downtime.

Containers, dumpsters & trailers

Floor rebuilds, plate patch-ins, rail and hinge repair, door hardware. Roll-offs and dump bodies brought back into service instead of replaced.

On-site fabrication & modification

Brackets, reinforcements, plate work, and modifications built and burned in at your location — no haul-off, no shop queue.

WPS-04 / CREDENTIALS

Certified. Mobile. Accountable.

Welding to a certification isn't paperwork — it's the difference between a bead that looks right and a joint that holds under load. My name is Stefanus Pretorius, and as an AWS certified welder, every structural connection I burn in is done to procedure: correct prep, correct rod, correct passes.

The rig is fully self-contained — machine, power, gas, and consumables ride with me. Your job doesn't wait on a shop schedule, and your steel never leaves the site.
