  • 1

    Stringer padding means that the base metal surfaces are to be:

    built up uniformly using stringer beads.

  • 2

    A root pass is produced when the:

    first penetrating bead is at the root of the joint.

  • 3

    Weave beads are deposited when the electrode is:

    moved forward and side to side while welding.

  • 4

    A cover pass is a:

    thin weave or a series of passes used as the final layer of weld metal.

  • 5

    What is the main purpose of pausing on the edges of a weave bead?

    to obtain a blend to eliminate undercut at the toes of the weld bead.

  • 6

    Electrode angle is:

    normally one half of the angle of the joint.

  • 7

    When the arc length is increased during welding, what happens to these characteristics? a) penetration ____________ b) puddle fluidity ___________

    penetration decreases puddle fluidity increases

  • 8

    8. What are two (2) commonly used methods for striking the arc with SMAW ?

    tapping method and scratch method.

  • 9

    9. Where should you strike the arc on a stop/restart?

    start the arc within the weld zone where the arc marks are to be remelted with the weld progression.

  • 10

    11. A normal arc length is considered equivalent to the:

    diameter of the core wire of the electrode.

  • 12

    13. What is the best method for determining the current setting for an electrode ?

    set current according to the manufacturers' recommendations and then test on a piece if scrap approximately the same thickness as the metal needed for weld project.

  • 13

    14. What should you do to maintain a normal arc length with electrodes that have high iron powder coatings?

    keep the flux coating in contact with the metal surface.

    deeper penetration with decreased puddle fluidity.

  • 15

    16. What electrode inclination is recommended for the first pass of a 2F weld in 10mm (3/8") material using a 3.2mm (1/8") E4310 (E6010) electrode?

    5° - 30° backhand

  • 16

    17. What type of bead is usually used for the cover pass on a 2F weld on 10mm (3/8") material?

    stringer bead

  • 17

    18. What procedure is recommended to complete a 3F weld using E4310 (E6010) electrodes on 10mm (3/8") material?

    use one root bead followed by a weave fill and a weave cover pass

  • 18

    21. A quick test for polarity can be done using which electrode ?

    E4310 (E6010)

  • 19

    22. Changing the inclination of the electrode in relation to the direction of travel:

    affects the depth of penetration

  • 20

    23. The number and letter combinations 3F and 2G, for example, represent:

    the required position and type of weld

  • 21

    26. Why is it so important to remove slag between passes on a multi-pass weld?

    to help prevent slag inclusions between passes

  • 22

    27. How should you position yourself relative to the weld?

    so that your body is supported and you are able to see the weld zone clearly

  • 23

    28. Which electrode normally requires a manipulative welding technique when doing stringer beads on the flat position

    E4310 (E6010)

  • 24

    29. Which electrode normally uses a drag technique when doing stringer beads?

    E4914 (E7014)

  • 25

    30. A fillet weld is placed on the underside of the joint with one vertical leg and one horizontal leg is:

    a horizontal overhead fillet weld
