Which evaluation method seeks to identify how a component could fail and what the consequences would be, to prioritize improvements?

• A. Root cause analysis
• B. Forensic analysis
• C. Failure analysis
• D. Failure modes and effects analysis

Answer: (D)

Failure Modes and Effects Analysis is a proactive risk assessment that identifies how a component or weld joint could fail and what the consequences would be, so you can prioritize improvements before problems occur. It asks, what potential failure modes could happen, what effects those failures would have on function, safety, or service life, and how likely each failure is and how easy it would be to detect. By evaluating severity, occurrence, and detection, you build a risk priority that guides where to focus design changes, process controls, or inspection methods to prevent issues. In welding, you might consider possible failure modes such as porosity, cracks, lack of fusion, or misalignment, and trace their potential impacts on strength, leak-tightness, or durability, then implement actions to reduce those risks. Other approaches analyze failures after the fact to determine causes and prevent recurrence, which is reactive rather than preventive.
