Nick Break and Fracture Test Quiz

What is the primary objective of the nick break test?

• To assess the color of the weld

• To determine the internal quality of the weld metal

• To measure the temperature of the weld

• To examine the fractured surfaces for external defects

Which welding process was used to join the specimen in the experiment?

• MIG welding

• Stick welding

• FCAW

• TIG welding

What angle should the bevel be prepared at for the nick break test?

• 90 degrees

• 60 degrees

• 45 degrees

• 30 degrees

What type of defects can the nick break test reveal?

• Internal defects like gas pockets

• Color variations

• Surface scratches

• Weld bead height

What is the first step in the procedure for the nick break test?

• Bevel preparation

• Cutting the specimen using plasma cutting

• Applying force to the specimen

• Examining the fracture surface

What should be done to the bevelled surface before welding?

• It should be coated with oil

• It should be cleaned

• It should be painted

• It should be heated

What was the first applied force recorded when the specimen broke?

• 300 psi

• 400 psi

• 500 psi

• 200 psi

What is one of the internal defects mentioned that can be spotted during the examination of the fracture surface?

• Surface roughness

• Color changes

• Gas pockets

• Cracks

Why is it important to remove slag after welding?

• To prevent gas pockets and porosity

• To increase the weight of the weld

• To improve the appearance of the weld

• To enhance the color of the weld

What conclusion can be drawn regarding the weld penetration based on the applied force before the specimen broke?

• The weld penetration was not deep

• The weld penetration was adequate

• The weld penetration was excessive

• The weld penetration was deep
