🔍 Key Concepts

• Melting point relationship between solder and base metals • Purpose of flux in soldering • Differences between soft solder and hard solder/brazing

💭 Think About

• Think about what would happen to the base metals if the solder needed a much higher temperature than the metals themselves. • Consider what property of solder allows you to melt it and flow it onto the joint without damaging or melting the pieces you are joining. • Ask yourself: does flux primarily change the melting point of solder, or does it serve another main function in the soldering process?

✅ Before You Answer

• Verify which option correctly describes the relative melting point of solder compared to the metals being joined. • Confirm the true role of flux (such as Borax) in soldering and brazing. • Check your knowledge of what is typically meant by hard solder and whether it must have a specific composition like lead and tin.
