Refinement of Metal :
Apart from protecting the weld pool form the ambient atmosphere, the coating, acting as a flux also partly removes oxygen from the molten metal by de-oxidation. The oxides being lighter than metal formed by de-oxidation of the weld pool floats up and is removed along with the molten slag, SpatFree 113 helps to refine the weld metal and improves the mechanical properties. Slag does not stick to the surface and is easily removed. Deep penetration of weld metal is yet another achievement.
