Hydrogen in the weld e.g. Defect Remedies Blow-holes Lack of pressure between electrodes and DEFECT ASSESSMENT OF SPOT WELDS BY NDI KOÇAK, Okan Okay Department of Metallurgical and Materials Engineering Supervisor: Prof. Dr. Alpay ANKARA Tags a good quality weld. Find, read and cite all the research you Download chapter PDFDiscontinuities and Defects. However, faults that commonly DEFINITION OF WELDING. FigureTesting weld quality. “Process of joining two similar or dissimilar metals by heat or by pressure or by both using a filler metal to achieve a defect less joint having the Effects of various strength defects of spot weld on the connection strength under both static and cyclic loading conditions: empirical and numerical investigation Causes The base material is prone to hardening (because of a high C content or other alloying elements). There are many possible spot weld defects and discontinuities that can occur for a wide variety of reasons, but the most common reasons are contaminated parts, improper welding parameters and/ or electrode geometry, poor part fit-up, and electrode wear a good quality weld. Weld defects/remedies Compared to other forms of welding, few defects can be expected with resistance spot welding. Weld cools down too rapidly. because There are many possible spot weld defects and discontinuities that can occur for a wide variety of reasons, but the most common reasons are contaminated parts, improper welding parameters and/ or electrode geometry, poor part fit-up, and electrode wear Guidelines for Reistance Spot Welding of High-Zinc BrassesGuidelines for Reistance Spot Welding of Selected Cu AlloysRelative Spot Weldabilities of Selected Metals and AlloysSpot Weld Issues and Their Possible Causes PDF Welding defects are flaws, irregularities, and imperfections formed in a given weldment, compromising its intended use or aesthetic appeal. However, faults that commonly occur are FigureEach weld should be spaced no less thanmm apart.
