Welding Defect - Porosity | Types of Gas Cavity | Herringbone/Worm Hole Porosity | Causes & Remedies
Welding Defects can be defined as the irregularities formed in the given weld metal due to wrong welding process or incorrect welding patterns, etc. The defect may differ from the desired weld bead shape, size, and intended quality. Welding defects may occur either outside or inside the weld metal. Some of the defects may be allowed if the defects are under permissible limits but other defects such as cracks are never accepted.
Gas Cavities are common in weld. If not removed it can harm the entire structure. This video explains why they are formed and how they can be reduced. Explanation is given with images & Radiographs
Types of Gas Cavity
1. Gas Pore / Pin Hole
2. Blow Hole
3. Uniformly Distributed Porosity
4. Cluster Porosity
5. Herringbone Porosity / Worm Hole Porosity
6. Root Piping
Type of Shrinkage Cavity
1. Crater Pipe
