Study Notes
Visual Inspection of Welds According to ISO 5817
- Porosity is a cavity-type weld discontinuity formed by trapped gas during solidification, with types such as isolated, scattered, piping, elongated, aligned, and cluster.
- Acceptance criteria for porosity according to EN ISO 5817 includes maximum single pore size and maximum cluster diameter, with different limits for weld width.
- Undercut is a groove melted into the base metal adjacent to the weld toe or root, with specific acceptance criteria for maximum depth according to EN ISO 5817 and AWS D14.4.
- Underfill refers to incompletely filled groove weld condition, with acceptance criteria for maximum depth according to EN ISO 5817 and AWS D14.4.
- Overlap is the protrusion of weld metal beyond the weld toe or root, with EN ISO 5817 not permitting overlap and AWS D14.4 allowing none.
- Convexity in fillet welds has specific acceptance criteria for maximum permitted dimensions according to EN ISO 5817 and no limit according to AWS D14.4, controlled by the limit on toe reentrant angle.
- Weld reinforcement is the excess weld metal in butt welds, with specific acceptance criteria based on the angle of reinforcement for both EN ISO 5817 and AWS D14.4.
- Arc strike is a discontinuity resulting from an arc, with specific characteristics and associated processes.
- Visual inspection of welds according to ISO 5817 includes the evaluation and measurement of different discontinuities and weld conditions using specific tools and criteria.
- Different acceptance criteria and limits for various discontinuities and weld conditions are outlined in ISO 5817 and AWS D14.4, providing standards for weld quality assessment.
- The evaluation of welds according to ISO 5817 involves understanding the specific characteristics and measurement methods for different discontinuities and weld conditions.
- ISO 5817 sets specific standards and criteria for the visual inspection and evaluation of weld discontinuities and conditions, providing guidelines for assessing weld quality.
Test your knowledge of visual inspection of welds according to ISO 5817 with this quiz. Explore the acceptance criteria, specific discontinuities, and measurement methods outlined in the standard, and assess your understanding of weld quality assessment.
