The ISO3D.GAUSS Application
Thick Plate Temperature Contours for a Distributed Heat Source
ISO-3D.GAUSS is a general purpose application for determining the temperatures adjacent to a weld when three dimensional (3D) heat flow predominates.
Unlike ISO-3D which simulates a point heat source, ISO-3D.GAUSS allows the user to specify a spot diameter up to 5 mm wide.
ISO-3D.GAUSS is valuable to simulate defocused laser beams, GTAW arcs, and other distributed heat sources. The user must input the weld procedure and ISO-3D.GAUSS will graphically produce the temperature fields in the surrounding base metal for the chosen metal or alloy. For small diameter heat sources the application will return the point source solution results.
The model is based on the Eagar and Tsai integral solution to the conduction heat flow equation for a moving Gaussian distributed source. ISO-3D.GAUSS can be used for gas tungsten arc welding, plasma arc welding, oxy acetylene welding, laser welding, and electron beam welding.
ISO-3D.Gauss 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.
