  • Method and system for controlling weld geometry features for improved fatigue performance of fabricated structures
    Patent number: 6362456
    Abstract: Surfaces of a weld seam are measured to determine weld seam characteristics such as weld seam profile, seam shape, misfit in a seam, seam gap, and surface irregularities. A desired weld bead profile is predicted based on the weld seam profile. Optimal welding parameters for the weld process are determined to achieve the desired weld bead profile. As the weld bead is applied along the weld seam, weld bead characteristics are measured to define the actual weld bead profile. The desired weld bead profile is compared to the actual weld bead profile and the weld process is modified if there is a difference between the actual weld bead profile and the desired weld bead profile. Modifications may include changing wire speed, travel speed, torch position, torch angles, or other various welding parameters.
