Cap undercut is a weld defect characterized by a groove or depression along the top surface (cap) of a weld bead. This defect occurs when excessive welding parameters or improper welding techniques cause the weld metal to erode or undercut the edges of the weld bead, leaving a concave or undercut profile. Cap undercut can […]

Burn through is a weld defect that occurs when excessive heat causes the weld metal to penetrate completely through the base material, resulting in a hole or void in the weld joint. This defect can compromise the structural integrity and mechanical properties of the weld, leading to potential issues such as reduced strength, increased susceptibility

Cluster porosity in welds is a defect characterized by the presence of multiple, closely spaced porosity or gas pockets within the weld metal. This defect occurs when gas, typically hydrogen, becomes trapped in the weld pool during solidification, resulting in the formation of clustered porosity. Cluster porosity can significantly compromise the mechanical properties and structural

Concave root weld is a weld defect characterized by a depression or concavity in the root of the weld joint. This defect occurs when the weld metal does not adequately fill the joint root, resulting in a hollow or undercut appearance at the root. Concave root welds can compromise the structural integrity and mechanical properties

Excessive root penetration is a weld defect that occurs when there is an overabundance of weld metal at the root of the weld joint, resulting in excessive penetration into the base material. This defect can compromise the structural integrity and mechanical properties of the weld, leading to potential issues such as reduced strength, stress concentration,

Lack of root fusion with misalignment is a weld defect that occurs when there is incomplete fusion between the weld metal and the base material at the root of the weld joint, compounded by misalignment between the mating surfaces of the joint. This defect can significantly compromise the structural integrity and mechanical properties of the

Excess penetration and piping are two related weld defects that occur when there is excessive penetration of the weld metal into the base material, often resulting in the formation of a “pipe-like” structure at the root of the weld joint. This defect can compromise the structural integrity and mechanical properties of the weld, leading to

Lack of root fusion is a weld defect that occurs when there is incomplete fusion between the weld metal and the base material at the root of the weld joint. This defect can weaken the weld joint, leading to potential failure under load and compromising the structural integrity of welded components. Let’s delve into this

Lack of root penetration in welds is a defect that occurs when the weld metal fails to fully penetrate the joint root, leaving a void or gap between the weld and the base material. This defect is a critical issue in welded structures, as it compromises the structural integrity and mechanical properties of the weld
