Zinga Galvanising Can Be Welded Over
ZINGA Galvanising is one of the few non specialized coatings that can be welded and applied over welds.
The welding of steel coated with ZINGA film galvanising (max. 60 μm DFT) is possible without excessive zinc fumes because the heat of the approaching weld bead burns off the organic binder well below the melting point of zinc.
The remaining zinc dust is removed from the weld zone by convection leaving the weld-area free from contamination.
Another big advantage is the small ‘burn back’ from Zinganised steel that is welded. In epoxy paints, this can be tens of centimeters (to meters), with ZINGA Galvanising, this burn back is limited.
ZINGA Galvanising can also be applied on welds without the needs of any special surface preparation (cleaning and roughening of the surface is necessary).
