Introduction to Steel Bridge Design Session L1

Steel Bridge Fabrication

This session will address the fabrication process of steel plate and box girders. All steps will be presented, from cutting the plates to size and fitting and welding the plates together to form the girders, to the fitting of the field splice connections. The impact of design on fabrication costs will be discussed, and recommendations will be made on design features from a fabrication standpoint. The welding processes used to join the plates including submerged arc weld, flux cored electrode, and narrow gap electroslag welding will be described. The inspection techniques and requirements used to ensure the quality of the welds will be presented. The session will conclude with a glimpse into the future of fabrication showing the virtual assembly process.

This presentation is part of the Introduction to Steel Bridge Design webinar series.
