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

Abstract

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.
