🔍 Key Concepts

• Understanding how tube ends are modified to accept another tube of the same size • Differences between swaging, flaring, and belling as metal-forming processes • How each process changes the inside vs. outside diameter of the tubing

💭 Think About

• Which term describes making one tube end larger so another tube of the same size can slip inside? • For each option, imagine what the tube end would look like after the process: is it narrowed, widened, or just lengthened? • Which process is commonly used to create a socket or cup-like end on a pipe or tube for joining?

✅ Before You Answer

• Identify which process specifically increases the diameter at the tube end to allow insertion of another tube • Eliminate any option that mainly reduces diameter or just lengthens the metal without forming a socket • Think about plumbing or piping joints: what is the name for the expanded end that accepts another section of pipe?
