🔍 Key Concepts

• Arc welding vs resistance welding – how is the heat created? • Role of flux coating on the electrode – what does it do during welding? • Differences between shielded metal arc, flux cored arc, and submerged arc processes

💭 Think About

• Which process specifically uses a stick-like electrode that is coated in flux and melts as you weld? • Which process uses pressure and electrical resistance between two pieces rather than an open electric arc? • Which processes usually involve continuous wire feed and/or granular flux poured over the arc instead of a single coated rod?

✅ Before You Answer

• Identify which option is commonly known as "stick welding" in industry terms. • Check which method is defined by an electric arc between a flux-covered electrode and the base metal (not separate flux, not resistance pressure). • Eliminate any option that mainly uses continuous wire or pressure/spot contact instead of a single flux-coated electrode rod.
