🔍 Key Concepts

• Welding penetration and how it is affected by heat input • Relationship between amperage (current), electrode size, and travel speed • Effect of travel speed on bead shape and penetration depth

💭 Think About

• Ask yourself: What change will actually increase the heat going into the base metal, not reduce it? • Think about how a larger electrode affects the required current and the amount of metal deposited versus penetration. • Consider what happens to penetration if you move faster versus slower with the electrode.

✅ Before You Answer

• Verify which options would increase heat input into the joint versus decrease it. • Check which action would tend to give deeper fusion into the base metal, not just a wider bead. • Eliminate any choices that would reduce arc time or current density at a given point on the metal.
