Q2. What is hot working and cold working
Ans. 
Hot working and cold working are metal forming processes used to shape materials at different temperatures.
• Hot working involves shaping materials at high temperatures, making them easier to deform without cracking or fracturing.

• Cold working involves shaping materials at room temperature or below, increasing their strength and hardness but also making them more brittle.

• Examples of hot working include forging and extrusi...read more
