🔍 Key Concepts

• Oxyacetylene flame types and how they affect the metal (oxidizing, neutral, carburizing) • Behavior of high carbon steel and non‑ferrous alloys when overheated or chemically attacked by the flame • Which flame gives least chemical change to the base metal during welding or hard-facing

💭 Think About

• Think about which flame composition (more oxygen, balanced, or more acetylene) is least likely to add or remove elements from the weld area • Consider how an oxidizing environment versus a carbon-rich environment will affect high carbon steels and non‑ferrous alloys like monel • Ask yourself: for hard-facing and special alloys, do we want the flame to change the metal’s composition, or keep it as close to original as possible?

✅ Before You Answer

• Review the characteristics of an oxidizing flame (sound, cone shape, and its effect on metal surfaces) • Review the characteristics of a carburizing (reducing) flame and how it can add carbon to the weld area • Identify which flame is described as having no chemical effect on the molten metal and is therefore preferred for most welding operations
