Cracking in Hot-dip Galvanized Welded Joints of SteelPlatform Structures – Mechanism of Failure and Prevention

A zinc coating is commonly used on structural steels to prevent corrosion. The structure is dipped in a hot bath of liquid zinc, which when cooled, provides to protective layer. However, after the coating process, cracking has been found in the welded joints of the structural steel. The proposed research aims to determine the cause of the cracking by investigating the construction process, the chemical make-up of the steel and the impact of the coating process. The partner organization will benefit from this study because it will be able to prevent any future failures and improve the quality of their structures. The partner organization will be able to protect their structures from corrosion without the impending threat of unpredictable cracking.
