The ISO-3D Application
Thick Plate Temperature Contours
ISO-3D is a general purpose application for determining the temperatures adjacent to a weld when three dimensional (3D) heat flow predominates. The user must input the weld procedure and ISO-3D will graphically produce the temperature fields in the surrounding base metal for the chosen metal or alloy.
The model is based on the Rosenthal moving point source solution to the conduction heat flow equation. The output graphics depict a heat source traveling over a semi-infinite plate. ISO-3D calculates peak temperatures and several quality parameters including melting efficiency, temperature sensitivity, and power sensitivity .
ISO-3D is applicable to any fusion welding process where the heat source is moving and melting of the base metal occurs. ISO-3D can be used for gas tungsten arc welding, plasma arc welding, oxy acetylene welding, laser welding, and other processes where filler metal is not deposited.
ISO-3D currently can be used for 19 metals and alloys: 304, 15-5PH, and17-4PH stainless steels, 1018, HY80, and HY130 steels, Hastelloy C4, C22, and B2, Kovar, 1100 and 6061 Aluminum, Ti-6Al-4V, Inconel 625, and 718, Nickel 200, 110 Copper, Tin, and Molybdenum.
