1. Which type of process is also known as fabrication process?
a) casting
b) forming
c) joining
d) none of the mentioned
View Answer
Explanation: Joining process is also known as the fabrication process. In fabrication process, product is made from raw materials and not from ready made components.
2. Which type of manufacturing process can fabrication process be termed?
a) primary
b) secondary
c) tertiary
d) none of the mentioned
View Answer
Explanation: Fabrication process is also known as secondary manufacturing process. Fabrication process doesn’t produce raw material. It produce products from raw materials. That’s why it is known as secondary process.
3. Which of the following process is not included in fabrication process?
a) welding
b) riveting
c) pressing
d) surface finish
View Answer
Explanation: Welding, riveting and pressing are included in fabrication process, Where as surface finish is included in machining process.
4. Which of the following pair is the part of fabrication process?
a) welding and metal removal
b) brazing and sintering
c) cohesion and sintering
d) all of the mentioned
View Answer
Explanation: Metal removal is the type of machining process and cohesion is included in casting process. Rest are included in fabrication process.
5. Which of the following fabrication process is mainly responsible for the fabrication of very high pressure boilers and nuclear reactors?
a) welding
b) sintering
c) brazing
d) pressing
View Answer
Explanation: Invention of welding has made a revolution in the fabrication process. Complex fabrication processes are also possible because of welding.
6. Which of the following is not the type of conventional welding process?
a) gas welding
b) friction welding
c) resistance welding
d) air welding
