Final answer:

Porosity in welding is the main concern for the inspector due to its impact on weld strength and structural integrity.


Explanation:

Porosity is the quality issue that the inspector would be concerned about. Porosity in welding occurs when gas pockets or voids are trapped in the weld metal due to inadequate shielding, incorrect gas flow, or contaminants. These holes weaken the weld and can lead to structural failure.
