  1. Which welding process uses a consumable wire electrode fed automatically through a gun under a shielding gas?

    Answer: MIG (GMAW)

    MIG/GMAW feeds a continuous consumable wire through the gun while shielding gas protects the weld pool.

  2. What is the primary purpose of flux in welding?

    Answer: To shield the weld from atmospheric contamination

    Flux creates a protective gas or slag that prevents oxygen and nitrogen from contaminating the molten weld.

  3. Which metal has the highest electrical conductivity commonly used in shop wiring?

    Answer: Copper

    Copper is among the best conductors of electricity, making it standard for wiring.

  4. When using an oxy-acetylene torch, which gas is the fuel?

    Answer: Acetylene

    Acetylene is the fuel gas and oxygen supports its combustion to produce a high-temperature flame.

  5. What does porosity in a finished weld indicate?

    Answer: Trapped gas bubbles weakening the weld

    Porosity is gas pockets trapped in the weld metal that reduce its strength.

  6. Which tool is used to remove slag after stick welding?

    Answer: Chipping hammer

    A chipping hammer breaks off the hardened slag coating left by the flux.

  7. Increasing the amperage on a welder generally does what to penetration?

    Answer: Increases penetration

    Higher amperage delivers more heat, producing deeper weld penetration.
