Failure Analysis
Flaw analysis is the systematic investigation of irregularities or failures in welded structures to determine the causes.
Physical-Chemical Mechanism of Action
Flaw analysis involves precisely examining weld defects to identify the underlying causes. This can be done through visual inspection, metallurgical testing, or specific analyses like radiography.
Metallurgical Relevance & Welding Risks
Flaw analysis is crucial for improving welding processes and avoiding failures. Without a thorough flaw analysis, recurring problems cannot be detected and corrected, leading to safety risks and high costs.
Shop Practice & Instructions
1. Identify the specific flaw or failure in the weld.
2. Use appropriate inspection methods such as visual inspection, ultrasonic testing, or radiography.
3. Document the results in detail and compare them with standards and specifications.
4. Analyze the causes of the flaws and develop corrective actions to improve the welding process.
