A method for providing an analytical solution for a thermal history of a welding process having multiple weld passes (606-1, 606-2, 606-3). The metho d includes the steps of inputting a plurality of files and parameters, preprocessing information from the plurality of files and parameters to determine a set of conditions associated with the welding process, determini ng a region of influence of at least one heat source (608) used in the welding process as a function of the set of conditions, determining a plurality of point heat source solutions within the region of influence, determining a temperature solution for each weld pass (606-1, 606-2, 606-3) as a function of a superposition of the plurality of point heat source solutions, and determining the thermal history of the welding process as a function of the temperature solutions.
