What steel fabrication can teach structural engineers

Many young structural engineers can analyse a steel connection on screen, but have little idea how the steel is actually cut, fitted and welded in a workshop.

This video is worth watching.

The fabricator is making an L-shaped joint from I-sections by hand. There is no BIM model or shop drawing shown in the video. What you can see is a strong grasp of geometry, careful setting out, precise cutting and the workmanship needed to bring the pieces together.

Watch how the cuts relate to the flanges and web. Watch how the pieces are checked and adjusted before welding. That is practical knowledge a structural engineer should have, even if they will never make the joint themselves.

Of course, a neat fit-up does not tell us whether a connection meets its design requirements. That still needs engineering design, a suitable welding procedure and inspection.

But the lesson here is simple: if you design steel structures, spend time in a fabrication workshop. Understanding how a detail is actually made will make you a better engineer.

One more thought: this approach is best suited to minor or light-duty structures. It would not be my first choice for major or heavy-duty steelwork.

With AI-powered robots advancing so quickly, I doubt many young people will want to learn and carry on this kind of hands-on craftsmanship. A sad thought, but probably the truth.
