Welding Electrode Calculation

The document provides diagrams and equations for calculating welding consumable consumption for ferritic steel butt and fillet joints. Figure 2 shows the calculated consumption of welding consumables for butt joints as a function of plate thickness, welding process, groove angle, and root opening. Figure 3 shows calculated consumption for fillet joints as a function of fillet size, welding process, and reinforcement size. The consumption in kilograms is calculated using the weld area, weld length, specific gravity of the weld metal, and deposition efficiency of the welding process.

Fundamentals of CO2
Arc Welding We recommend you to use the following
diagrams for a quick estimation of the
Welding of Medium /
High Carbon Steels and consumption of welding consumables for

Welding References Figure 2 shows the calculated consumption of


welding consumables as a function of plate
Textbooks of Welding thickness, welding process, groove angle, and root opening for butt joints. With respect to fillet joints, Fig. 3 shows
the calculated consumption of welding consumables as a function of fillet size, welding process, and reinforcement
size. These diagrams were developed using the calculations obtained by the following equation for both groove and
fillet welding joints under the prerequisites given below.

C = [(A1 + A2) x L x G/E] x 1/10

Where
C: Consumption of welding consumables (kg)
A1: Area of Section A1 weld metal (mm2) ― Fig. 1
A2: Area of Section A2 reinforcement (mm2) ― Fig. 1

L: Weld length (m)


G: Specific gravity of weld metal (7.85 g/cm3)
E: Deposition Efficiency (%) ―
SMAW covered electrodes: 55%
GMAW solid/metal-cored wires: 95%
FCAW flux-cored wires: 90%
SAW solid wires: 100%
