Elongated slag line weld defect refers to the presence of elongated or extended slag inclusions within the weld bead. This defect occurs when slag particles are not properly removed during the welding process and become elongated or stretched along the length of the weld bead. Elongated slag line defects can compromise the structural integrity and […]

Slag line weld defect occurs when slag gets entrapped in the weld metal during the welding process. Slag is a byproduct of the flux used in welding processes such as shielded metal arc welding (SMAW) or flux-cored arc welding (FCAW). When slag becomes trapped in the weld metal, it forms a line or inclusion within

Root undercut in welds is a defect characterized by a groove or depression along the root of a weld joint, typically at the juncture between the base materials. This defect occurs when excessive welding parameters or improper welding techniques cause the weld metal to erode or undercut the edges of the base materials, leaving a

Porosity in welds is a defect characterized by the presence of small voids or cavities within the weld metal. These voids are typically caused by the entrapment of gas, such as hydrogen, nitrogen, or oxygen, during the welding process. Porosity can significantly compromise the mechanical properties and structural integrity of the weld, leading to issues
