Welding Steel Before and After Galvanizing (Best Practices & Recommendations)
Welding Steel Before and After Galvanizing (Best Practices & Recommendations)
Designers opt for galvanization as the corrosion protection system for structural steel fabrication since it ultimately provides the most sustainable solution with the lowest carbon footprint. The welding of steel prior to or after galvanization is common, both are compatible with the objective of providing excellent corrosion protection. The processes, however, involve specific considerations, recommended as best practices, to ensure the viability of both the structural integrity and the intended corrosion protection.
It is key to reiterate some of the key considerations for the proper preparation and the importance of adherence to guidelines, which are essential for the successful welding of pre or post galvanized steel. Further outlined will be the proper welding practices before galvanizing and how they play a significant role in eliminating distortion. In addition, some hints about how welded surfaces can be re-galvanized. A targeted review of some examples of varying welding projects with specific requirements will illustrate how the best practices can be applied by proper planning and execution.
