  • 1

    An electrode inclination of 0° with a normal arc length produces a:

    medium width bead with smooth metal flow

  • 2

    What is the purpose of tacking the ends from the back side of your open groove weld coupons?

    to ensure full root bead fusion at the ends of the plates

  • 3

    Unless it is otherwise specified, what grade of Steel is the permanent backing material to be?

    if the backing is to be permanent, the grade of material is to be the same as the material being joined.

  • 4

    What is the purpose of the backing material on welds with a backer?

    to support and shape molten weld metal at the root of the joint

  • 5

    What do you have to be very careful of when welding a joint with a permanent backer?

    you need to ensure a full fusion between the base metal and the backing

  • 6

    What is a good rule for past placement when multi-pass welding?

    always achieve penetration into the narrowest portion of the joint

  • 7

    What action increases penetration on a root of a 2G weld?

    shorten the arc length

  • 8

    For complete penetration on an open root Groove weld using E4310 (E6010) electrodes, you must:

    Carry a continuous keyhole

  • 9

    What weld position generally results in the highest amount of distortion?

    2G

  • 10

    When you deliberately shorten the arc length, you can expect to increase:

    penetration and decrease puddle fluidity

  • 11

    Which of the following would most likely produce lag inclusions in multi-pass welds?

    low current settings with a long Arc length

  • 12

    What is required to ensure that full fusion is obtained on a root pass of a 1G position weld on 10mm (3/8") material?

    progression maintaining a continuous keyhole

  • 13

    Is it necessary to remove scale and rust from the base metal?

    yes

  • 14

    What joint configuration is suggested for a 1G weld with a v-groove preparation on 10 mm (3/8") material with a 60° included angle?

    Root face preparation is comparable to the Gap

  • 15

    How many passes would you likely use for a 1G weld with a v-groove preparation on 10 mm (3/8") material using 3.2 mm (1/8") E4310 (E6010) for the root and a 2.5 mm E4918 (3/32 E7018) for the fill and cap passes

    3 or 4 passes

  • 16

    When doing the root bead of a 1G weld what action would you take if the keyhole is not melting evenly in the groove?

    immediately adjust the electrode angle to force the keyhole into the center

  • 17

    What is the main purpose of the hot pass?

    to penetrate into the root and melt out the slag or undercut

  • 18

    Most codes and standards do not accept a crack or open defect:

    3.2 mm (1/8") length measured in any direction

  • 19

    What is the root spacing for a CSA 2G with backing test weld?

    8 mm 5/16 in

  • 20

    What weld position generally results in the highest amount of distortion?

    2G
