Weld Imperfection Classification
Weld defects are classified into categories like gaps, overfill, and distortion. Each defect has a certain size and frequency that are relevant for quality assurance.
Physicochemical Mechanism of Action
Weld defects form through deviations in the welding process, like insufficient mixing or missing energy. These lead to imbalances in the metal structure and result in visible defects.
Metallurgical Relevance & Welding Risks
Missing classification of weld defects can lead to inadequate quality assurance. Gaps can cause cracks, excess weld metal hurts the mechanical properties, and distortion changes the structure. These defects reduce the service life and reliability of the welded construction.
Workshop Practice & Instructions
Use a microscope to classify weld defects. Note the size in millimeters and the frequency per meter of weld. Follow the quality standards of the materials and processes used. With frequent or severe defects, check the welding parameters and the tool.
