Figure 5 Load curve.
Thermal boundary conditions, given by Eqs. (3) and (4), occur at all the surfaces except the adiabatic plane at the longitudinal symmetry plane of the final joint; in the same manner, for numerical simplicity, the surfaces of the chamfer hollow have been considered adiabatic before supplying the filler material.
Thermal properties dependent on temperature46,47 are reported in Figure 6A. In order to take into account the transformation phase in the thermal analysis, a latent heat per mass unit, a solidus temperature and a liquidus temperature equals to 277000 J/kg, 1495 °C, 1540 °C respectively, have been used, whereas the temperature dependent heat loss coefficient H , applied on the surfaces, is shown in Figure 6B.
