🔍 Key Concepts

• Shielded metal arc welding (SMAW) and the purpose of electrode coatings • What happens to molten metal when exposed to oxygen and nitrogen in the air • Difference between operator safety, arc stability, and protection of the weld puddle

💭 Think About

• Think about what the welding arc and molten metal are exposed to in the open air and what problems that can cause for weld quality. • Consider what the coating does when it burns off during welding—what does it create around the arc and weld puddle? • Ask yourself which options describe protection of the weld area versus protection of the person or the electrical circuit.

✅ Before You Answer

• Identify which choice specifically involves protecting the molten metal and arc from the surrounding atmosphere. • Eliminate any answers that mainly deal with welder safety rather than weld quality. • Check which option best matches what a flux coating is known to do in common shipboard welding processes.
