What is staircase effect? A welding operation on an aluminum alloy makes a groove weld.
The cross-sectional area of the weld is 30.0 mm2. The welding velocity is 4.0 mm/sec. The
heat transfer factor is [0.92+{AAA/(20+YY)}] and the melting factor is [0.48+
{AAA/(20+YY)}], where AAA are the last three digits and YY are the first two digits of your
student ID. The melting temperature of the aluminum alloy is 667°C. Determine the rate of
heat generation required at the welding source.
