The ISOEDGE Application

Edge Weld Temperature Contours

View the ISOEDGE Control Panel

ISOEDGE is a general purpose application for determining the temperatures adjacent to an edge weld. Edge welds are often used to minimize heat input to temperature sensitive components.

The user must input the weld procedure and ISOEDGE 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 along the edge of two plates clamped together. It is applicable to any fusion welding process where the heat source is moving and melting of the base metal occurs.

ISOEDGE calculates peak temperatures and several quality parameters including melting efficiency, temperature sensitivity, thickness sensitivity, and power sensitivity.

ISOEDGE 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.
