Porosity is a cavity-like discontinuity and occurs due to the entrapment of gases in the molten weld pool. These entrapped gases don't get a chance to escape from the molten weld pool and hence cause porosity.
<h3>Which discontinuities are caused during welding?</h3>
Weld discontinuities can be defined as "an interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the weld." Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.
