What is Cluster Porosity welds defect? how to determine and prevent it

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

Excess penetration and piping welds defect? how to determine and prevent it?

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
