Which process involves joining two metals by melting them at the joint?
Welding
To determine which process involves joining two metals by melting them at the joint, we need to consider the main characteristics of each option provided:
- Riveting: This is a process of joining two or more metal parts using rivets. Riveting does not involve melting the metal at the joint. Instead, the rivet is inserted into the pre-drilled holes and then deformed to hold the parts together.
- Brazing: In this process, two metal parts are joined by heating them and using a filler metal that melts at a lower temperature than the metal parts being joined. The base metals do not melt; only the filler metal does.
- Soldering: Similar to brazing, soldering involves joining two metal parts with a filler metal that has a lower melting point, but at even lower temperatures compared to brazing. The base metals do not melt.
- Welding: Welding involves melting the base metals at the joint. The metals are fused together by the application of heat, pressure, or both, with or without a filler material. This process forms a strong joint as the base metals mix together.
Based on these explanations, welding is the process that involves melting the metals at the joint to join them together. Hence, the correct answer is welding.
Welding creates a very strong bond since the metals themselves are melted and fused together, making this technique ideal for heavy-duty structural applications.
