Five places where the joint quality decides the project.
We're focused on critical piping - the kind of piping where one failed joint can contaminate a $40M batch, shut down a fab, or leak liquid coolant into a hyperscaler rack. Five industries make up most of our deployment footprint, and they share an engineering thread.
Particle control drives the whole gas-line construction discipline: closed-chamber welding, 360-degree inert envelopes, and inner-bead oxidation-control targets become part of the project preparation before a fab build-out can proceed.
The compact form factor of the FXT20 power source matters here more than anywhere else. Fab cleanroom retrofits frequently can't accommodate full-size welding rigs, so equipment size and site access must be reviewed before retrofit planning.
Engineering checks
- Inner bead target verified by sample weld and project acceptance criteria
- Particle-control requirements reviewed for cleanroom-grade assembly
- SUS316L VIM/VAR & electropolished tubing compatibility
- 3.175 mm - 25.4 mm OD covered by C5 / C10 / C40 heads
- SEMI F20-type inner-bead and weld-record documentation per joint
WFI loops, CIP/SIP piping, and bioreactor process lines are judged by inspection records, not verbal assurances. The auditor wants two things: an inner bead they can inspect and a data log they can trust per joint. Both are direct outputs of an orbital system.
The reason ASME BPE became dominant in this space is auditability. Once your fabrication shop is logging voltage, current, gas flow, and operator ID per joint, QA has structured records to review instead of relying only on loose paperwork.
Engineering checks
- ASME BPE-type inner-bead color and dimensional inspection targets
- Per-joint data log indexed by drawing reference
- FDA cGMP traceability across operator, program, material
- EHEDG hygienic-design cleanability for food/dairy lines
- 1/2" - 4" OD coverage on C10 / C40 / C80 / C120 heads
High-density liquid cooling requires tight leak control. A single weld failure in a direct-to-chip manifold can put high-value compute equipment and uptime at risk. This makes welding repeatability and traceability commercially important.
The mechanical constraint is space: cooling manifolds get fabricated inside the rack envelope, not in a clean fabrication shop. The FXT20 was designed for this geometry as a compact digital power source, so welding can be planned around the install envelope.
Engineering checks
- Compact head + power source for in-rack welding
- Programmable for 316L stainless and copper-nickel
- Per-joint data log for hyperscaler QA pipelines
- Leak-tight inner bead validated to ASHRAE liquid cooling
- 10-50 mm typical OD on C10 / C40 / C80 heads
Field retrofits and instrumentation tubing are won at the joint. The variability you fight in an oil and gas job site - wall thickness drift, ambient temperature swings, operator fatigue across long shifts - is exactly what orbital welding standardizes away.
Open-frame K-series heads cover 2" through 24"+ Sch. 40 piping with AVC arc-length control that compensates for the real-world geometry of installed pipes. Micro-orbital heads handle 1/4" instrumentation tubing on the same digital interface.
Engineering checks
- AVC arc-length control across pipe out-of-roundness
- Field-ready open-frame head, single-operator setup
- Position 1G - 6G coverage for fixed pipe
- Programmable parameter library across material grades
- Micro orbital heads for 1/4" instrumentation lines
A heat exchanger fabrication run is hundreds to thousands of tube-to-tubesheet welds. Each one has to pass radiographic acceptance. A small change in inspection acceptance, multiplied across the bundle, can affect the margin on the build.
PT40 and PT80 heads were designed for this geometry: tubesheet clamping, four-quadrant programmable parameters, AVC across each rotation, and automatic positioning between adjacent tubes. Actual acceptance rates depend on material, WPS, fixture condition, and inspection plan.
Engineering checks
- Per-quadrant parameter control for tube-to-tubesheet asymmetry
- AVC arc-length control across each rotation
- Automatic head positioning between adjacent tubes
- Per-joint log indexed by tube-row coordinate
- 16 mm - 38 mm typical OD, programmable to 3.5 mm wall
"All five industries share one engineering reality: the joint that fails first is the joint that wasn't a senior welder's best work. Orbital welding helps turn validated parameters into repeatable shop practice."
