Question

P=3000W f1=0.9 f2=0.5 A=15mm2 travel speed=?

Answer 1

The Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s. See the computation below.

What is travel speed?

The travel speed of the welding flame or gun across the workpiece is simply measured in millimeters per minute.

Travel speed, along with voltage and amperage, is one of three factors in arc welding that affect the amount of heat input.

What is the calculation that justifies the above answer is?

We are given the following:

Melting temperature = 1650 K

k = (3.33 * 10⁻⁶) * (1,650)²

k = 9.066 J/mm^3

The formula for velocity here is given as:

V = f1 * f2 * Rh / (k*A)

V = 0.9 * 0.6 * 3000 / (9.066*25)

V = 7.147 mm/s

Hence, the Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s.
