Which of the following welding processes uses a non-consumable electrode?
- A.
Shielded Metal Arc Welding (SMAW)
- B.
Gas Metal Arc Welding (GMAW)
- C.
Gas Tungsten Arc Welding (GTAW)
- D.
Flux-Cored Arc Welding (FCAW)
Correct Answer
C. Gas Tungsten Arc Welding (GTAW)Explanation
In GTAW, also known as TIG welding, the electrode is made of tungsten, a metal with an extremely high melting point. This allows the electrode to conduct the welding current and generate the arc without being consumed in the process. In contrast, SMAW, GMAW, and FCAW all use consumable electrodes that melt and become part of the weld.Rate this question:

Any small piece of metal should be ___________ while drilling.
- A.
Clean
- B.
Oiled
- C.
Clamped
- D.
Held
Correct Answer
C. ClampedExplanation
When drilling, it is important to secure the workpiece in place to prevent it from moving or spinning. Clamping the metal ensures that it remains stable and stationary during the drilling process, allowing for accurate and precise drilling. This helps to prevent any accidents or damage that could occur if the metal were to move or slip while drilling. Therefore, clamping is necessary to maintain the safety and effectiveness of the drilling operation.Rate this question:

Oily rags should be placed in a
- A.
Trash can
- B.
Closed metal container
- C.
open metal container
Correct Answer
B. Closed metal containerExplanation
Oily rags should be placed in a closed metal container to prevent any potential fire hazards. Oily rags can spontaneously combust due to the heat generated by the oxidation process of the oils. By placing them in a closed metal container, it helps to contain any heat and prevents the oxygen from reaching the rags, reducing the risk of ignition. This is why a closed metal container is the safest option for disposing of oily rags.Rate this question:
