Galvanizing-Induced Distortion in Steel Plate Girders. II: Effects of Welding and Galvanizing Practices
This paper, the second of a two-part series, presents a parametric study investigating the influence of welding and galvanizing practices on the susceptibility of welded plate girders to distortion during and after galvanizing. Three methods of welded fabrication were studied: welding in lay-down position, welding in the trough, and welding in the vertical position. In addition, galvanizing dipping and extraction speed, dwell time in the zinc bath, and dipping angle were examined as parameters. It was found that welding in the vertical position corresponded to the least distortion during galvanizing, especially for unstiffened plate girders. Dipping speed was also identified as an important parameter for reducing distortion, and faster dipping and extraction speeds resulted in less distortion during and after galvanizing. The results of this study provide guidance to engineers, galvanizers, and fabricators to minimize steel plate girder distortion so that they can more confidently use hot-dip galvanizing to protect their bridges, and the paper describes a modeling methodology that will enable future research in this field.
