The 3-dimensional thermal analysis for the Keyhole plasma arc welding Technique

Subramaniyan Raj, Rama iyer


The evolution of temperature profiles and weld pool geometry in the course of distinct welding among 2205 duplex stainless steel and A36 low carbon metal the use of keyhole plasma arc welding has been simulated the use of a three dimensional numerical warmness switch and fluid go with the flow model. An adaptive warmth supply is proposed as a heat supply model for acting a non-linear temporary thermal evaluation, based totally on the configuration function of keyhole plasma arc welds. Temperature profiles and solidified weld pool geometry are provided for three welding warmth enter. The reversed bugle form parameters (width of fusion zone at both pinnacle and bottom surfaces) of the weld pool geometry capabilities for a multiple 2205–A36 weld joint are summarized to effectively provide an explanation for the observations. The model become additionally applied to keyhole plasma welding of 6.eight mm thick similar 2205 duplex stainless steel joint for validation. The simulation effects have been compared with independently received experimental statistics and excellent agreements have been obtained.
