The right fit across three platforms RotoweldLJ WeldingHGG Group
Hard Productivity & Speed

You can't hire your way out. Automate ahead.

The American Welding Society projects the U.S. will need roughly 330,000 new welding professionals by 2028, with only two workers entering for every five who retire. Automation closes the gap the hiring market can't.

The human factor

Up to five times the output of a manual, two-welder shop – one operator per cell.

100%

Uncompromising consistency

Mechanized, repeatable welds. Inspection-ready quality on every shift, not "good on a good day."

9–12 mo

Timeline security

Built to meet or beat aggressive project windows when go-live dates carry penalties.

330k

The labor gap

New welders the U.S. needs by 2028 (AWS). The shortage automation is built to answer.

The Core Framework

Your metal's journey.

Every fabricated part travels the same road. We automate the three stages in the middle, where your schedule and margin are won or lost, and leave the bookends to your line.

Arrival
Logistics

Cut + Prep

Smart 3D profiling & bevel prep, round and square.

Tack + Prep

Precise fit-up and positioning for a repeatable root.

Weld

Automated root, fill & cap. ASME-ready, every joint.

Meat & Potatoes: where we work
Hydro
Testing
Paint
Finishing

The stages between Cut and Weld are where schedules slip and margin leaks. Automate the middle, and the whole job moves.

Family matters.

Rotoweld, LJ Welding and HGG are independent, family- and founder-led businesses, not faceless corporations. That heritage shows up where it counts: partners who stand behind their machines for the long haul, share your values, and pick up the phone. When you work with The Fab Doctor, you're buying into relationships, not just equipment.

Industry Hubs

One capability, mapped to your world.

Every vertical has a different bottleneck. We match exactly one automation capability to each, so you start where it moves the needle for you.

Data Centers

Automated pipe welding

500–1,200 chilled-water spools per facility, all on a penalty-backed clock. Automated welding runs stations in parallel and turns a 120-day spool program into 40.

LJ Pipe Titan · high-volume spool welding

Oil & Gas

Orbital heavy-wall welding

Large-bore, heavy-wall pressure pipe with zero margin for a bad joint. Automated orbital welding delivers ASME Section IX consistency at deposition rates a manual crew can't touch.

Rotoweld 3.0 · 2"–48" pipe spools

Healthcare

Precision GTAW automation

Hygienic, critical-service stainless lines demand flawless, contamination-free welds. Automated GTAW holds thin-wall precision that passes the strictest medical-gas and process specs.

LJ GTAW systems · thin-wall stainless

Shipbuilding

3D structural profiling

Miles of beam, box and profile to cut, cope and bevel before a single weld. Smart CNC profiling turns days of manual layout and grinding into a repeatable, fit-up-ready cut.

HGG RoboRail · beam, box & profile

Aerospace / Infrastructure

Extreme-scale handling

From flight-critical assemblies to 60"+ grow-line pipe with 2" walls, the weld is only as good as the handling under it. High-torque positioning keeps massive parts turning smoothly and precisely.

LJ positioners & grow lines · up to 60,000 lb

Proven On The Floor

Fabricators like you already run these platforms.

You're not the test case. Shops across North America have put this equipment to work and reported the results.

Kg per arc-hour with the Rotoweld is about 4× greater than with a manual process. And don't worry – it'll pass RT.

When you get used to a low rework rate like we have with the Rotoweld, you can't go back.

Jason Haskin, Facility Engineering ManagerPerma-Pipe · Rotoweld 3.0

From having five or six guys processing parts that take 10 minutes each, to a single operator machine that's doing them in 40 seconds, is kind of a no brainer.
