What is the term for joining parts by melting them together?

1. Adhesive bonding

2. Clamping

3. Fusion welding

4. Soldering

The correct answer is: Adhesive bonding

The correct answer is "Fusion welding." Fusion welding is the process of joining two pieces of metal together by melting and fusing them at the joint. This process creates a strong bond between the two parts, making it a common method used in metal fabrication and repair. The other options are: A. Adhesive bonding: This involves using adhesives or glues to join parts together, which is a method different from melting the parts together. B. Clamping: Clamping is a method used to position and hold parts together during the welding or bonding process, but it is not the term for joining parts by melting them together. D. Soldering: Soldering is a process that joins two metals by melting a filler metal with a lower melting point and flowing it into the joint. While soldering involves melting, it is typically used for joining smaller or delicate parts compared to fusion welding.
