Soldering, Brazing, and Welding Differences

This section discusses the distinctions between soldering, brazing, and welding based on temperature requirements, tools used, and the process of joining metals.

Temperature as a Determining Factor

• Soldering involves melting alloys below 840 degrees Fahrenheit.

• Brazing or hard soldering occurs above 840 degrees Fahrenheit.

Tools Used in Different Processes

• Brazing requires high temperatures necessitating a torch or furnace.

• Soft soldering can be done with a regular soldering iron or heat gun.

Process of Joining Metals

• Solder has a lower melting point than the metal in soft and hard soldering processes.

• In welding, workpieces are melted along with filler metal to form a weld pool through fusion.

Key Takeaways

• Temperature range is crucial in distinguishing between soldering, brazing, and welding processes.

• The melting range of the solder depends on the alloy used, varying with different mixtures of metals having distinct melting points.
