  • 1

    What position(s) can SAW be used in ?

    flat and horizontal positions

  • 2

    What type(s) of output slope do SAW power sources use ?

    CC and CV

  • 3

    What duty cycle rating is recommended for most SAW power sources ?

    100%

  • 4

    SAW may be used in the semi-automatic or automatic operation modes

    true

  • 5

    What is the advantage of using an ac power source for SAW ?

    it minimizes arc blow with multiple wire set-ups

  • 6

    What will usually result if the drive roll pressure is set too low ?

    the wire electrode will slip and feed erratically

  • 7

    How will the arc react if the flux layer is to shallow ?

    the weld will be flashing and will likely result in porosity

  • 8

    Which is helix ?

    the space between two unrestrained loops of wire

  • 9

    What type (s) of drive rolls are normally used with SAW ?

    knurled or V-groove

  • 10

    What type of wire feed set-up is used with CV power sources ?

    constant speed

  • 11

    To increase arc length when you are welding with SAW, you would:

    increase arc voltage

  • 12

    When using SAW, an increase in arc voltage produces a:

    wider arc stream and shallower penetration

  • 13

    When is DCEN used with SAW ?

    when shallower penetration is required

  • 14

    What diameters are SAW electrodes wires available in ?

    1.6 mm to 6.4 mm (1/16" to 1/4")

  • 15

    What is the main difference between the CSA and AWS classification systems for SAW electrodes wires ?

    CSA uses the metric system to measure tensile strength values.

  • 16

    Which type of SAW flux is generally used for the addition of alloying elements ?

    active flux

  • 17

    Which type of flux can be re-used ?

    fused

  • 18

    What should be done with SAW fluxes after they have become exposed to moisture?

    they should be dried or rebaked according to manufacturer specifications.

  • 19

    Are higher deposition rates obtainable with SAW process ?

    yes

  • 20

    Is SAW easily done in all positions ?

    no
