Consider a situation in which a welding operation is being performed with V = 20 volts, I = 200 A, and the cross-sectional area of the weld bead is 30 mm2. Estimate the welding speed if the workpiece and electrode are made of (a) aluminum, (b) carbon steel, and (c) titanium. Use an efficiency of 75%.
A)35 mm/s
B)34.5 mm/s
C)36 mm/s
D)46 mm/s

The welding speed can be estimated using the formula: Speed = (Efficiency * Power) / (Cross-sectional Area * Heat of Fusion). Given the same efficiency and power, the speed will be similar for different materials. The calculation results in approximately 34.5 mm/s.
