weldderived
Weldderived is an adjective used in materials science and welding engineering to describe characteristics, outputs, or phenomena that originate from welding processes or the weld itself. It encompasses the metallurgy of the weld metal, the transformations in the heat-affected zone, residual stresses, distortion, and defect patterns that arise from heat input, cooling rates, and process parameters.
Etymology and usage: The term is informal and not part of formal welding standards; it is used
Applications and scope: In design, evaluation, and quality assurance, analysts distinguish weldderived effects when assessing joint
Limitations and considerations: Because it lacks standardization, weldderived definitions vary between organizations and projects. To avoid
