TIG and MIG Welding Services in Southern California

TIG, MIG and robotic welding, weldments and full assembly in Fontana, California — performed in the same facility that cuts and forms the parts, so the whole build stays under one roof.

Welding sits in the same building as the tube laser, the plate laser and the press brakes. That matters more than it sounds: parts never ship between vendors mid-build, nothing waits on someone else's schedule, and when a fit-up problem appears there is one shop accountable for it rather than three pointing at each other.

Because the cut parts arrive with keys, tabs and etched part numbers already in them, assemblies locate themselves. Less fixturing, less measuring, fewer mistakes on long weldments.

The weld department runs steel, stainless and aluminum. Manual work goes to five Miller Millermatic 252 MIG stations and seven TIG stations (three Miller Syncrowave 350 LX and four Everlast machines), on four ground 5 × 10 ft fixture tables that keep long frames flat and square. Production and repeat weldments run in a robotic cell: a FANUC ArcMate 210iD/12L long-reach robot on a Lincoln Power Wave power source.

Finished weldments are checked on the same inspection equipment as our machined parts: a Zeiss Spectrum CMM, a Keyence WM-C6025 wide-area CMM and a Keyence VL 3D scanner, under the same AS9100D quality system.

We handle assemblies from small brackets through large frames and structures, including large, heavy-section aluminum weldments. The practical size limit is what fits through our 14 ft wide doors and on a semi trailer. Customers are across the Inland Empire, Los Angeles and Orange County, and parts ship across Southern California. If your weldment needs a material, process or certification you do not see here, ask; the answer is usually a phone call.

Common questions

Which welding processes do you run?

TIG and MIG, manual and robotic, for weldments, sub-assemblies and full assemblies from small brackets through large frames and structures. Production and repeat weldments run in a FANUC robotic welding cell.

What materials do you weld?

Steel, stainless and aluminum, including large, heavy-section aluminum assemblies. If your assembly calls for another material, ask when you request the quote.

How large a weldment can you build?

Size is limited by transport and our doors: if a weldment fits through a 14 ft wide door and on a semi trailer, we can build it.

Where do you serve?

We are in Fontana, California, in the Inland Empire, and weld for customers across San Bernardino and Riverside counties, Los Angeles and Orange County. Parts ship across Southern California.

Do you cut and form the parts you weld?

Yes. Welding sits in the same building as the tube laser, the plate laser and the press brakes, so parts never ship between vendors mid-build and one shop is accountable for fit-up.

How do you keep long weldments aligned?

Cut parts arrive at the weld bay with keys, tabs and etched part numbers already in them, so assemblies locate themselves with less fixturing and less measuring off a print.

What quality certifications does the weld shop hold?

CalWest is AS9100D and ISO 9001:2015 certified and ITAR registered.
