This article provides an overview of fractography as it applies to metal weldments and presents examples of various fracture surface morphologies to demonstrate how fractographic analysis can be used to determine the cause of weld failures. It identifies weld fractography principles and details several weldment-specific geometric and metallurgical considerations. The role of the weld-cracking mechanisms on the resultant fracture surfaces is described, along with example micrographs and fractographs of weldments. Common discontinuities related to welding processes and their impact on the resulting fracture behavior and surfaces are covered, as well as the common fractographic features related to fatigue failures of welds.
