Method and system for restoring parent metal properties across welds |
摘要 |
A method, with an associated system, for providing a cast component comprises annealing heat treatment to reduce casting stresses; initial machining the cast component; initial nondestructive testing (NDT) the machined cast component to identify NDT indications in the cast component; treating and removing NDT indications from the machined cast component; weld upgrading the treated and removed NDT indications from the machined cast component, the weld upgrading providing stress relief; intermediate nondestructive testing the cast component to identify NDT indications in the weld upgraded cast component; normalizing and temper heat treatment of the cast component; second intermediate nondestructive testing the cast component to identify NDT indications in the cast component; further treating and removing NDT indications from the cast component; post-normalization and temper weld upgrading the treated and removed NDT indications providing stress relief; and final nondestructive testing the cast component to identify NDT indications in the cast component.
