Need help with determining the rate of heat generation required at the welding source to accomplish a weld.A fillet weld is used to join two medium carbon steel plates each having a thickness of 5.0mm. The plates are joined at a 90 degree angle using an inside fillet corner joint. The velocity of the welding head is 6mm/sec. Assume that the cross section of the weld bead approximates a right isosceles triangle with a leg length fo 4.5mm, the heat transfer factor is 0.80, and the melting factor if 0.58.
Determine the rate of heat generation required at the welding source to accomplish a weld.
the material is steel and the melting temperature is 1760 K
