🔍 Key Concepts

• Arc welding process – how the electrode and base metal are protected during welding • Flux and shielding – what flux does when it melts and forms slag/gas • Oxidation of molten metal – what happens to hot metal exposed to air

💭 Think About

• Think about what happens to the molten weld pool if it is exposed directly to air at very high temperature. • Consider what flux turns into when heated: slag and/or shielding gas. What is their main protective function? • Which choice best matches the idea of protection of the molten metal rather than changing shape, heat, or depth of weld?

✅ Before You Answer

• Identify the main protective job of flux during arc welding, not a side effect. • Ask: which option describes chemical protection of the molten metal, not mechanical distortion or weld geometry? • Verify which answer choice relates to preventing reaction with oxygen in the air at high temperatures.
