Weld Quality Audit
A weld quality audit is a systematic and independent review of welding manufacturing processes to ensure compliance with quality standards and regulations. It serves to identify defects and improve weld quality.
Physical-Chemical Mechanism
A weld quality audit involves checking various physical and chemical properties of a weld, such as hardness, stresses, porosity, and microstructure. It is performed to ensure the weld meets specific technical requirements.
Metallurgical Relevance & Risks in Welding
A failed audit can lead to defects in weld quality, such as insufficient stress buildup, porosity, or incorrect microstructure. This can cause cracking, failure, and reduced service life of the component.
Shop Practice & Action Guidelines
To successfully carry out a weld quality audit, follow these steps:
1. Preparation: Define the quality standards and codes to be checked.
2. Execution: Inspect the weld using visual inspection, mechanical tests, and chemical analysis.
3. Evaluation: Document the results and identify any defects or deviations from the specifications.
4. Improvement: Take corrective actions to fix the issues found and refine the welding process.
