Machine bases, carts, tables, guards and frames welded in steel, stainless and aluminum, machined after welding when precision demands it.

TIG and MIG welding

Welding is easy; welding without the part moving is not. We build structures that later have to receive a machine, a robot or a precision device, so we control deposition sequence, distortion and stress relief — and when the print calls for it, we machine the mounting surfaces after welding to guarantee flatness and position.

Machine bases and frames

A twisted welded base ruins the alignment of everything mounted on it. We build frames from tube and plate, control distortion with welding sequence and alternating tacks, and grind or mill the mounting faces so the machine seats on the correct plane.

Carts, tables and workstations

We design and build transport carts, assembly tables, racks and stations sized to the available space and to operator ergonomics, with industrial casters, removable trays and a powder-coated finish.

Repair and modification

We recover damaged structures, reinforce zones failing from fatigue and modify existing equipment for a new line or a new part number, instead of replacing the whole structure.

How we keep the structure from twisting

Distortion is not hammered out at the end: it is prevented during the process. We work on an assembly table with the piece clamped, apply alternating tacks on opposite sides instead of running a continuous bead, and control heat input so stress does not concentrate in one zone. On structures that will later receive a machine, we relieve stress before machining the mounting faces, because a plate that moves after being milled is no longer flat. That care is the difference between a base that aligns the equipment and one that forces you to shim it.

FAQ

Frequently asked questions

Can you weld stainless without staining it?

Yes. We use TIG with the right filler and shielding gas, back-purging when the application calls for it, and we passivate the heat-affected zone so the stainless keeps its corrosion resistance.

Can you machine the structure after welding it?

That is exactly what separates this from a general fab job. We weld, relieve stress and then machine the critical faces for real flatness and position.
