______________ is a process in which two close-fitting parts are joined by using a filler material which
is heated above its melting point and distributed in the gap by capillary action.
Show answer & explanation
Correct answer: D
Explanation
The Correct answer is option 4 i.e. Brazing
- Brazing is a process that joins two close-fitting parts using a filler material. The filler material is heated above its melting point and distributed between the parts by capillary action.
- Brazing is often used to join aluminum, cast iron, magnesium, copper and copper alloys, and silver.
- Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity.
