FB2M, a French heavy steel fabricator, says Visometry's Twyn augmented reality software has cut its most demanding visual inspections from almost a full working day to 30 minutes or less. The company puts the reduction at up to 90 percent. FB2M has used the tablet-based tool since 2025 for visual inspections and basic geometric checks on very large welded assemblies.

Before Twyn, inspectors worked from customer-supplied 2D drawings with tape measures and calipers, and signed off each line of the inspection report by hand. FB2M adopted Twyn after a customer recommended it. "Some of our most demanding inspections used to take almost an entire working day with 2D drawings," says Christian Mallick, Technical and Quality Director at FB2M. "With Twyn, we can now complete the same inspection in 30 minutes or less."

Twyn now runs at several points in production. Inspectors use it to check and approve subassemblies, then for final acceptance of finished parts such as crawler frames for mobile cranes and slewing platforms for excavators. They also prepare the final acceptance reports in the tool, which FB2M describes as standardized digital documentation.

The quality numbers moved too. FB2M reports that customer-side nonconformities involving missing parts have dropped 50 percent since Twyn was introduced, and that internal nonconformities from assembly errors have also decreased. Quality inspectors previously needed help from someone in production to carry out their checks. They now do them on their own.

For quality managers working on large weldments, the practical detail is where Twyn sits in the process. FB2M uses it alongside established methods, including non-destructive testing of welds, rather than in place of them.

Three quality inspectors use Twyn on tablets every day, and production managers occasionally use it on iPhones. FB2M lists additional in-process inspections among its gains, alongside shorter inspection times and more consistent checks.
