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>

Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.
