  • Method for controlling distortion of a material during a weld process
    Patent number: 7006958
    Abstract: A method for controlling distortion of a material during a weld process. The method includes modeling the weld process of the material, determining distortions produced by the weld process, determining a plurality of simulated induced distortions in the model to offset the produced distortions, generating a plurality of actual induced distortions in the material as a function of the simulated induced distortions, and performing the weld process on the material.
    Type: Grant
    Filed: December 4, 2000
    Date of Patent: February 28, 2006
    Assignee: Caterpillar Inc.
    Inventors: Patrick J. Crilly, Yi Dong, Keith A. Herman, Yuping Yang, Frederick W. Brust, Wayne R. Tanner
  • Method for determining a model for a welding simulation and model thereof
    Patent number: 6768974
    Abstract: A method for determining a model for a welding simulation, and the associated model. The method includes the steps of determining a history annihilation model of a material being welded, determining a strain hardening model of the material being welded, determining a three-dimensional virtual elements detection model of the material being welded, and incorporating the above models into a constitutive model for the welding simulation.

  • Method for providing an analytical solution for a thermal history of a welding process
    Patent number: 6398102
    Abstract: A method for providing an analytical solution for a thermal history of a welding process having multiple weld passes. The method 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, determining a region of influence of at least one heat source 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 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.
