Metal surfacing is becoming the natural choice for reducing the consumption of expensive raw materials, processing cost and proper resource utilization.
Dilution is the key factor responsible for mechanical as well as metallurgical properties of the welded member and is defined as the change in chemical composition of a deposited filler material caused by the mixing with the base material or previously deposited weld material in the deposited weld bead.
