Detailed Solution
Download Solution PDFThe correct option is 4.
Explanation: -
Brazing -
- It is a solid liquid state welding process in which two metals are joined using filler material that flow via capillary action.
- Filler material used in this is Copper and Zinc Alloy.
- The melting point of filler material is less than that of parent material.
- Brazing Temperature is greater than 420°C.
Advantages-
- Thin sheet/parts which cannot be joined by welding can be easily joined by brazing.
- Corrosion resistance joints can be obtained by this method.
- It produces clean joint, needed little or no finishing.
- It does not change metallurgical characteristics of material due to low temperature of operation.
Disadvantages-
- Brazing is not suitable at higher temperature because of low melting point of filler material.
- The colour of brazed joint is different from the parent/base material.
- Brazed joints are weaker as compare to welded joints.
- Metals to be joint must be close to ensure the capillary action of filler material.
