Question

What is an advantage of hot working compared to cold working?

1) Fracture of the workpart is less likely
2) Fracture of the workpart is more likely
3) The workpart can be shaped more precisely
4) The workpart can be shaped less precisely

Answer 1

Hot working allows for more precise shaping of the workpart.

Step-by-step explanation:

Hot working is a process where a metal is shaped or formed at a high temperature, while cold working is done at or near room temperature. One advantage of hot working compared to cold working is that the workpart can be shaped more precisely.

For example, when a metal is heated, its atoms gain more kinetic energy, allowing them to move more freely and making it easier to reshape the metal. The higher temperature also reduces the strength and hardness of the metal, making it more malleable. This increased malleability allows for greater precision and control in shaping the metal.
