1 Calculating
Filler Metal Consumption The
number of pounds of welding electrodes or welding wire necessary to complete a
given weld joint may be
calculated by the formula: P
= WL
E Where:
P = Pounds
of electrode or wire required W = Weight
per foot of weld metal L
= Length of
weld (feet) E = Deposition
efficiency Weight
Per Foot of Weld Metal Calculating
the weight of weld metal requires that we consider the following items.
1. Area of the cross-section
of the weld. 2. Length
of the weld. 3. Volume
of the weld in cubic inches. 4. Weight
of the weld metal per cubic inch.
