What are pieces of slag or tungsten that are trapped in a weld deposit called?

Porosity
Undercut
Inclusions
Incomplete fusion

The correct answer is: Inclusions

Inclusions refer to the pieces of slag or tungsten that become trapped in a weld deposit during the welding process. These materials can be remnants of the welding electrode, flux materials, or other contaminants that do not properly melt or integrate into the weld. The presence of inclusions can lead to weaknesses in the weld and affect the overall integrity of the welded joint. When weld metal is not thoroughly cleaned or when the welding parameters are not appropriately controlled, these inclusions may occur. Proper welding techniques and post-weld cleaning processes are critical to minimizing their formation and ensuring strong, reliable welds.
