Ocena diagnostyki wpływu kolejności spawania nakładek stalowych w procesie sprężania technologicznego dźwigarów skrzynkowych.

In the paper there are presented diagnostic tests made on steel models of box girders. Diagnostics concerned the effect of compression plates welding sequence on final stress and deformation results of the realized technological process where the phenomenon of welding shinhage of additional plates welds was applied. On the base of diagnosis, the most affective sequence of compression plates welding has been determined for optimization of compression process.
