WebSlag inclusions are nonmetallic solid material entrapped in weld metal or between weld and base metal. In a radiograph, dark, jagged asymmetrical shapes within the weld or along the weld joint areas are indicative of slag inclusions. Incomplete penetration (IP) or lack of penetration (LOP) occurs when the weld metal fails to penetrate the joint ... WebIn welding, such non-metallic inclusions can increase the metals’ susceptibility to cracks and fatigue causing the structure to fail. For safety and quality, the integrity of the weld and …
