steddi makes rail welds measurable.
steddi (steddi.com.au, by Bartoleni Engineering & Consulting, Terrigal NSW) builds digital straight edges for rail weld alignment and grinding verification — deployed with Sydney Trains, Queensland Rail and Rio Tinto. This analysis examines the company, maps the qalarc project portfolio onto its roadmap, and reviews the global automatic welding systems landscape.

Four sections, three of them substance
What steddi is, where the qalarc projects overlap it, and what the automatic welding market means for both.
- 02steddi Analysis The products (ONE / MINI / GO), the manual straight-edge problem they replace, the standards they calibrate against, and the SWOT. →
- 03Project Overlap Five qalarc project areas — field intelligence, 3D terrain, data pipelines, custom-trained vision models, teleoperation — mapped onto steddi's roadmap. →
- 04Auto Welding The global automatic welding landscape: the Ukrainian KZESO/Paton lineage, Western incumbents, the Chinese wave, and why automation raises the value of independent measurement. →
- 05Roadmap Four phases from measurement device to system of record to closed loop — with a 90-day first phase built from existing qalarc systems. →
The measurement is the hard part. The data is the valuable part.
- Every steddi GO measurement is a data point — laser geometry, rail temperature, location, crew, timestamp — logged over Bluetooth to a companion app. Today that data largely stops at the phone.
- The natural next stage of the company is a data layer: capture in remote corridors, aggregate into track-level intelligence, visualise in 3D, and eventually close the loop with automated welding and grinding.
- That data layer is what the qalarc portfolio already does in other domains — offline-first radio intelligence, real-topography 3D visualisation, live anomaly-detecting data pipelines, and custom-trained on-device vision models.
- Hardware companies get commoditised when their measurement becomes a commodity. They get defensible when their data becomes the system of record for weld quality across a network.
