GALVANIZED STEEL

Use & Application
These consumables are developed for welding galvanized structural fabrications. The presence of micro-alloying elements is optimized to minimize zinc contamination in the weld pool, allowing welding directly onto the galvanized surface and minimizing spatter. It thus displays better welding characteristics compared to standard unalloyed wires. Good resilience at low temperatures. The use of thread with synergic inverter generators it allows to achieve optimal results. After welding, it's mandatory to restore the protective surface in the weld and HAZ area using products for cold galvanizing. Preheat and PWHT would often not be required but actual requirements will depend on grade and thickness of base material being welded. The required mechanical properties of a welded joint are readily achieved in C-Mn galvanized steels with the use of the appropriate welding consumables. However, the complex nature of the structural changes that occur during the weld thermal cycle does mean that some care is needed in assessing properties such as heat affected zone (HAZ) toughness and hardness.
Alloy type
Low alloy C-Mn steel, deoxidized with Ti, Al and Zr.
Microstructure
Predominantly ferrite.
Materials to be welded

Used to weld C-Mn and low alloy steels also with light surface contaminations and oxides, and for welding galvanized steels with tensile strengths of 580MPa.
