dc.description.abstract | Hot-dip galvanizing is the process of submerging steel elements into molten zinc
to form a metallurgically bonded zinc coating that serves as corrosion protection
for the steel substrate. Used with great success on an industrial scale for many
decades, hot-dip galvanizing is a ubiquitous process. On occasion, cracks in
steel members develop during galvanizing. While such cracking remains a poorly
understood phenomenon, previous research has attributed the formation of
cracks to the combined effects of residual strains introduced by welding and
temperature-induced deformations caused by the hot-dip galvanizing process.
This article presents thermomechanical analyses of a structural steel beam with
a welded double-angle connection detail where cracking occurred during
hot-dip galvanizing. Three-dimensional finite element models of the beam and
connection detail were analyzed using the finite element analysis software
Abaqus (Dassault Systèmes, Vélizy-Villacoublay, France). The welding process
was simulated using the Abaqus Welding Interface, maintaining the welding
sequence of the connection. After welding, the entire beam was subjected to a
temperature field that was specified through a user subroutine in Abaqus,
simulating the hot-dip galvanizing process. The temperature field had a bath
temperature of 450°C and a thermal cycle that included dipping, dwell time, and
removal from the bath. Material properties used in the simulation were nonlinear and temperature dependent. The parameters of the study were the welding
sequences, heat input during welding, and the depth of the double-angle
connection. It was observed that strain demands due to welding and hot-dip
galvanizing were high magnitude at the cracked location in the beam. The relative
significance of strain demands due to welding and of hot-dip galvanizing on the
propensity for the beam to develop cracks are discussed. | en_US |
