The ISOSPOT-2D Application

Thin Plate Spot Weld Temperature Contours 

View the ISOSPOT-2D Control Panel

ISOPOT-2D  is a general purpose application for determining the temperatures adjacent to a spotweld  when two dimensional (2D) heat flow predominates. The user must input the weld procedure and ISOSPOT-2D will graphically produce the temperature fields in the surrounding base metal for the chosen metal or alloy. 

 The model is based on the continuous line source solution to the conduction heat flow equation. ISOSPOT-2D can be used for resistance welding, pulse arc welding, laser spot welding, and other short duration welding processes where melting occurs very rapidly.

ISOSPOT-3D calculates peak temperatures and several quality parameters including melting efficiency, temperature sensitivity, thickness sensitivity, and peak power sensitivity . 

ISOSPOT-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.
