See ARC WELDING DEPOSITION EFFICIENCY and THERMAL SPRAYING DEPOSITION EFFICIENCY.

Deposition efficiency is the ratio of the weight of deposited metal to the net weight of electrodes or wire consumed, exclusive of any loss from stubs, or cut off.

An effective method for calculating the deposition efficiency for a given process is to use that process to deposit a measurable electrode weight on a clean plate of known weight, remove the slag and spatter, and re-weigh. (If wire is a factor, the method is the same as

above; wire weight is determined by weighing the reel of wire and subtracting the weight of the reel). The ratio of weight added to the plate to the weight of the electrode used is the deposition efficiency. Typical deposition efficiencies for various processes are shown in Table D- 1.
