"We had a certain respect for the cobot at first; most of us had never programmed one. In the end, we were surprised by how simple and user-friendly the system is."


– Marek Soukup, Welder & Cobot Operator, NN Steel


"The big advantage is the RB-X software. The controls are intuitive, you don't have to learn complicated programming, and if you understand welding, you can pick it up quickly."


– Marek Soukup, Welder & Cobot Operator, NN Steel

BUSINESS CASE

NN Steel, a Czech metalworking and fabrication company, sought to modernize its welding operations to hold consistent quality on repeat parts while facing the shortage of qualified welders. The company invested in an RBW cobot welding system, operated by its own welders, to raise productivity and free skilled staff for more demanding work.

PROBLEM 


The company faced growing challenges due to:

  • Repeat parts: frames, brackets, and smaller weldments, tying up skilled welders in routine operations.

  • Variation between manual runs, driving rework, and making the output harder to plan.

  • No robot programming experience on the team, and the expectation that automation would be complicated.

SOLUTION


After assessing how automation could fit its production, NN Steel selected RBW's cobot welding system for its intuitive no-code operation and fast onboarding.

  • The operator learned to build welding programs within a few hours; complete training took two days.

  • The RB-X software requires no programming background; welding knowledge is the only prerequisite.

  • One welder now covers the full cycle: part preparation, program setup, weld monitoring, and final quality control.

VALUE

  • Increased productivity on suitable parts by tens of percent, with fewer repairs.

  • Guaranteed consistent weld quality through constant speed, exact trajectory, and high repeatability.

  • Greater stability in production makes output easier to plan after several months of operation.

  • Physically less demanding work, as the cobot takes over routine and repetitive operations.

  • Welders gained time for more demanding work, preparing further orders and quality control.
