The work behind every weld we let leave the floor.
An orbital welding system is a process instrument. We treat it as one - calibrated, burned in, validated, and shipped with a parameter library that carries a senior engineer's judgment. Here's what that means in detail.
5-point pre-delivery inspection protocol: from component screening to sample-weld validation.
Component screening
Electrical consistency checks on every core PCB before the unit is assembled. Pulse-control boards, AVC modules, motor drivers, and gas-flow sensors are bench-tested against tolerance limits set in the original R&D validation.
Mechanical calibration
Weld head rotation accuracy measured against a calibrated reference. Gear-train backlash, AVC drive linearity, and concentricity all logged per unit. Out-of-spec units return to assembly.
Burn-in stress test
48 to 72 hours of continuous operation under simulated load. Catches early-life component failure before the unit reaches a customer floor. Temperature, current, and pulse stability are monitored throughout.
Gas-tight leak test
Shielding-gas integrity check on weld head chambers. Helium-grade leak detection where applicable. Any leakage at 0.5 bar above ambient sends the head back to assembly.
Sample weld validation
An actual orbital weld on representative tubing. Visual + dye-penetrant inspection of the inner bead. The sample weld coupon ships with the unit so the customer can verify against their own reference.
200+ orbital welding programs: indexed by material, OD, wall thickness, position, and shielding gas.
Every FYID power source ships with 200+ welding programs. Each program is a complete parameter set - peak current, base current, pulse frequency, travel speed, ramp profile, gas flow, post-purge - validated by our process team against a known material / geometry combination.
The library is indexed by six variables. When your operator picks a program, they're not guessing the parameters - they're inheriting the parameter decisions a senior process engineer already made. The library updates over the system's life; new validated entries ship as firmware.

- Shielding gas
- Argon / Ar/He blends / Ar/H / for stainless
- Joint type
- Butt / Socket / Tube-to-tubesheet
Per-joint orbital weld traceability: joint ID, program, operator, parameters, and inspection status.
The data logger is not an accessory. It is in the power source. FXT20 supports built-in printing and USB function per KB; project records are typically organized around joint ID, program ID, operator, timestamp, key welding parameters, and QC status.
The sample below is a traceability-field example for WFI / UHP projects. It is not a fixed report format for every customer; final fields should follow the customer WPS, inspection plan, and audit requirements.

"We don't build features. We close failure modes - one validated program at a time, one logged joint at a time, one shipped unit at a time."
