Question 1: What is the primary challenge when welding dissimilar metals in manufacturing?

Which action should you take?

Choose only one option

The material's color consistency

Selecting a compatible filler material that prevents cracking and poor fusion

Controlling the temperature of both materials

The aesthetic appearance of the joint

Question 2: What is the function of a weld root pass in a multi-pass welding procedure?

Which action should you take?

Choose only one option

To control the heat distribution in the joint

To remove impurities and contaminants from the joint

To create a strong bond between the base materials at the joint's root

To add filler material to the top layer of the joint

Question 3: Why is proper ventilation essential when working with certain chemicals in the fabrication shop?

Which action should you take?

Choose only one option

To maintain a comfortable temperature for workers

To prevent the buildup of toxic fumes that could lead to health hazards

To increase the efficiency of chemical processes

To reduce the need for PPE in the workplace

Question 4: What is the role of the cooling system in maintaining a high-performance laser cutting machine?

Which action should you take?

Choose only one option

To improve the clarity of the cutting lines

To speed up the cutting process by cooling the material

To prevent overheating and ensure consistent cutting quality

Question 5: What is the difference between MIG welding and flux-cored arc welding (FCAW)?

Which action should you take?

Choose only one option

FCAW uses direct current (DC) while MIG uses alternating current (AC)

MIG welding uses a shielding gas, whereas FCAW uses the flux in the core for shielding

MIG welding is best for thin metals, while FCAW is better for thicker metals

FCAW uses a continuously fed electrode while MIG uses a filler wire only

Question 6: In metal casting, which factor primarily influences the choice of alloy?

Which action should you take?

Choose only one option

Availability of the material in the local market

Aesthetic appearance of the part

Weight and cost

Melting temperature and fluidity
