SYSTEMATIC COLD WORKING OF WELDS

摘要

A method for welding a component (10) includes the steps of selecting a weld area (120) in the part which is located near a feature of interest; applying a weld (22 ) to a portion of the weld area (120), wherein solidification of the first weld (126, 158) causes deviation of the feature from a desired position; and cold working the first weld (126 , 158) so as to impart plastic deformation therein to a degree that material is extruded outward from the first weld (126, 158). The deviation of the feature is at least partiall y reversed. The method may include the step of applying and cold working a series of spaced- apart tack welds (126) in a defect, and then applying and cold-working a series of weld s between the tack welds (126).
