Surface Defects | Grain Boundaries and Stacking Fault | 2-D Imperfections in Solids

In this video, I will be discussing about 2-D imperfections commonly known as Surface Defects. These include Grain boundaries and Stacking faults.

As slamalaikum Sir , please tell me piping defect.

[@ProfDrVasimAShaikh]

Piping defect in materials refers to a type of internal defect that can occur in castings or welds. In castings, piping occurs when molten metal shrinks as it cools and solidifies, causing a depression or void to form at the top of the casting. This depression can create a pathway for liquid metal to be drawn out of the casting during solidification, leaving a tube-like void or "pipe" in the center of the casting. In welding, piping can occur when a void is formed in the center of the weld as the molten metal cools and solidifies. This can weaken the weld and make it more susceptible to failure under stress. Piping defects can be prevented by controlling the cooling rate of the metal during solidification, using proper casting or welding techniques, and ensuring that the molten metal is free of impurities that can contribute to void formation. Detecting and repairing piping defects can be difficult, and may require cutting into the casting or weld to remove the affected area.
