What is a key takeaway regarding bead quality from these TIG welding notes?

Explanation:
Bead quality is driven by weld protection. In TIG welding, keeping the shielding gas properly covering the weld pool protects the molten metal from air contamination, preventing oxidation and porosity. When gas coverage is good, you’ll see a clean, smooth, uniform bead with consistent width and penetration. If shielding is inadequate, contaminants enter the weld, giving defects and a poorer-looking bead. The other factors listed (gas use rate, arc voltage stability, tool wear) influence efficiency, arc behavior, or maintenance, but they don’t define bead quality as directly as proper weld protection does.
