The ISO-2D Application

Thin Plate Weld Temperature Contours 

View the ISO-2D Control Panel

ISO- 2D is a general purpose application for determining the temperatures adjacent to a weld when two dimensional (2D) heat flow predominates.

Many laser and electron beam welds can be represented with the 2D line source when full penetration is achieved.

The user must input the weld procedure and ISO-2D 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 line source solution to the conduction heat flow equation. The output graphics depict a heat source traveling over a rectangular plate. It is applicable to any fusion welding process where the heat source is moving and melting of the base metal occurs. ISO-2D calculates peak temperatures and several quality parameters including melting efficiency, temperature sensitivity, thickness sensitivity, and power sensitivity .

ISO-2D 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-2D 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.
