Rosenthal [25] used the following simplifying assumptions to derive simple analytical equations for heat flow in the workpiece during welding:

1 Steady‐state heat flow

2 Point heat source

3 Negligible heat of fusion

4 Constant thermal properties

5 No heat losses from the workpiece surface

6 No convection in the weld pool
