  • 1

    Temperature, Expresses in °F or °C, refers to the measure of the:

    intensity of energy

  • 2

    The term heat expresses

    quantity

  • 3

    Which is a common cause of distortion?

    unequal heating and cooling of welds

  • 4

    When heated evenly and without restraint, in which direction does metal expand?

    volumetrically (in all directions)

  • 5

    Transitional expansion occurs when a metal changes from:

    one crystalline structure to another

  • 6

    Which time of distortion results from shrinkage across the weld that tends to pull a member of a Tee joint toward the welded side?

    angular distortion

  • 7

    Which type of distortion results in overall reduction in the length of the weld?

    longitudinal distortion

  • 8

    Which type of distortion refers to the tendency (in butt joints) for the plates to draw together down the length of the joint as you are welding ?

    transverse distortion

  • 9

    What causes angular distortion in a Vee groove weld if the plates are free to move ?

    a non uniform contraction of the weld metal

  • 10

    What is the primary cause of distortion created from longitudinal shrinkage ?

    weld beads contracting upon cooling

  • 11

    What welding variable is more likely to have the plates of a butt joint draw together causing transverse distortion ?

    welding at a slower rate

  • 12

    What is one method you can use to correct angular distortion on butt joints ?

    weld on both sides

  • 13

    How can you reduce longitudinal distortion?

    keep weld reinforcement to a minimum

  • 14

    What is one method to reduce transverse distortion?

    use a fast deposition rate

  • 15

    What is a disadvantage to rigid clamping and fixturing ?

    some distortion can occur after releasing the clamping

  • 16

    What is one advantage of a jigging device ?

    it maintains accuracy of the finished product

  • 17

    Pieces of metal placed on either side of the joint that absorb the heat of the weld and help prevent distortion are called:

    chill strips

  • 18

    What is the purpose of balancing welds around the neutral axis of a worn shaft ?

    to equalize the contraction stresses of the welds

  • 19

    How can you help control distortion when welding light gauge metal m

    increase the number of tacks

  • 20

    Which fillet weld application produces the greatest amount of distortion ?

    multi-pass fillet welds with convex profile

  • 21

    What is one characteristic of a good welding design ?

    it uses formed or rolled sections

  • 22

    When several plates must be welded together with butt joints, what is the best weld sequence to control distortion ?

    weld from the centre and toward the outside in both directions

  • 23

    What is the advantage of using sub-assembleys ?

    they provide for more welds in the flat position
