Answer:
Listed Below
Step-by-step explanation:
Weldability which is also known as joinability is defined as the ease with which a material can be welded without producing any other effect .
Some factors which affect weldability are
1.Melting point of metal
- Higher the melting point lower will be the weldability.
2.Thermal conductivity
- Materials with higher thermal conductivity are difficult to join.
3.Reactivity
- If the material reacts with surroundings like water or air, it is difficult to weld.
4.Coefficient of thermal expansion(α)
- Higher the thermal expansion lower will be the weldability.
5.Surface condition
- The material with dirty surface is difficult to weld for example if a surface has oxide layer on it it become difficult to weld it.
