  • 1

    With GTAW, the heat of the arc is transferred to the work through a non-consumable:

    tungsten electrode

  • 2

    GTAW requires an inert gas to:

    shield the weld puddle

  • 3

    GTAW is used primarily when:

    high quality welds are mandatory

  • 4

    For what application would hot wire GTAW be used ?

    where high production welds are required

  • 5

    In what positions can GTAW process be used ?

    all positions

  • 6

    Which metal requires a full preheat when welded with the GTAW process ?

    cast iron

  • 7

    GTAW has an advantage over SMAW because it:

    can eliminate the need to use flux

  • 8

    When welding with GTAW, you should wear:

    dark-coloured, tightly woven clothing

  • 9

    When using GTAW, good ventilation is required in order to prevent:

    an oxygen deficiency

  • 10

    The arc radiation from GTAW reacts with elements in atmospheric air to form:

    O3 (ozone)

  • 11

    Ultraviolet radiation from GTAW can react with chlorinated degreasing solvents to produce:

    phophene gas

  • 12

    Pulsing the arc with GTAW is an advantage when:

    penetration on thin metals must be controlled

  • 13

    Welding machines designed for GTAW are:

    constant current (CC)

  • 14

    Which statement is true with respect to orbital GTAW ?

    it can be done without filler wires

  • 15

    Which of the following machines would be best suited for GTAW ?

    AC/DC rectifier

  • 16

    A post-purge control is designed to:

    keep gas flowing for a pre-set time after the arc is extinguished

  • 17

    What is the recommended current type for welding stainless steel ?

    DC electrode negative

  • 18

    Which current type produces the deepest penetration ?

    direct current electrode negative

  • 19

    Removal of aluminum oxide occurs:

    during the positive half of the AC cycle

  • 20

    AC high frequency is most suited for GTAW on:

    aluminum and magnesium

  • 21

    Continuous high frequency current is required when:

    a stabilized AC current is required

  • 22

    Which statement is true ?

    The EP and EN portions can be adjusted

  • 23

    A GTAW torch cap is the part of a GTAW torch that:

    protects the electrode from accidental arc strokes

  • 24

    A collet is a device in the GTAW torch that:

    positions the electrode and transfers current

  • 25

    The diameter of the nozzle is normally determined by:

    the size of the puddle and the electrode

  • 26

    To use continuous high frequency current, the nozzle must be constructed of:

    ceramic

  • 27

    What is the purpose of a regulator when used with GTAW ?

    to reduce supply pressure to a safe working pressure

  • 28

    A flowmeter is calibrated in:

    litres per minute or cubic feet per hour

  • 29

    What is the purpose of a flowmeter when used with GTAW ?

    to meter the flow of shielding gas
