Question

A GTAW operation is performed on low carbon steel, whose unit melting energy is 10.8 J/mm3. The welding voltage is 22 volts and the current is 149 amps. The heat transfer factor is 0.65 and the melting factor is 0.66. If filler metal wire of 3.9 mm diameter is added to the operation, the final weld bead is composed of 57% filler metal and the rest base metal. If the travel speed in the operation is 4 mm/sec, determine the feed rate (mm/sec, 1 decimal point) at which the filler wire must be supplied.

Step 1

Given: Voltage, V = 22 V Current, I = 149 A Heat transfer factor, η = 0.65 Heat input per second, \[ Q = V \times I \times \eta = 22 \times 149 \times 0.65 = 2131.7 \, \text{J/s} \] --- Show more…
