The framework almost nobody applies
EN 17460 replaces the DIN 6701 series and governs adhesive bonding of rail vehicles and their components. DIN 2304 does the same for other sectors. Both ask for what EN ISO 3834 asks of welding: a defined process, competent personnel and traceability.
Bonded joint design
We review the geometry before anything is built: overlap area, bond line thickness, stress distribution and, above all, making sure the load does not end up working in peel. A joint sized correctly for shear still fails if the real load lifts it from the edge.
Surface preparation
This is where the joint is won or lost: degreasing, activation, roughness and open time before application. The right adhesive on a badly prepared surface fails exactly as a good consumable does on a dirty joint preparation.
Process and personnel qualification
EN 17460 sets competence levels for the bonding coordinator and for the operators, just as EN ISO 14731 does in welding. We help define the process, qualify it and document the operators' competence.
Hybrid joints
Bonding combined with welding, riveting or bolting. This is where mistakes are easiest, because each technology brings its own standard and acceptance criteria, and someone has to decide which one governs the joint.
