Weld Defect Classification
Weld defect classification is a systematic grouping of irregularities into cracks, cavities, solid inclusions, and shape and dimensional deviations.
Physicochemical Mechanism of Action
Weld defects form through uneven stress distribution, missing filler material or mechanical disturbances during the welding process. These defects can cause chemical reactions in the metal or fail to absorb mechanical forces correctly.
Metallurgical Relevance & Welding Risks
Wrong classification of weld defects can lead to inaccurate repairs, which in turn leads to further defects and possible cracks in the part. It is crucial to identify the cause of the defects in order to take effective corrective measures.
Workshop Practice & Instructions
Use a standardized classification scale for categorizing weld defects. Document each defect class precisely and carry out targeted corrections. Pay attention to the correct application of the welding parameters and the quality of the material used.
