Answer 1

Intensity of energy

Question 2

Term heat expresses

Answer 2

Quantity

Question 3

Common cause of distortion

Answer 3

Unequal Heating and Cooling of welds

Question 4

Transitional expansion occurs when a metal changes from

Answer 4

One crystalline structure to another

Question 5

Which type of distortion results from shrinkage across the world that tends to pull a member of a t-joint towards the welded side

Answer 5

Angular distortion

Question 6

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

Answer 6

Longitudinal distortion

Question 7

Type of distortion that refers to the tendency in butt joints for the plates to draw together down the length of the joint as you are welding

Answer 7

Transverse distortion

Question 8

What causes angular Distortion in a V groove weld if the plates are free to move

Answer 8

The non uniform contraction of the weld metal

Question 9

Primary cause of distortion created from longitudinal shrinkage

Answer 9

Weld beads Contracting upon Cooling

Question 10

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

Answer 10

Welding at a slower rate

Question 11

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

Answer 11

Weld on both sides

Question 12

How to reduce longitudinal distortion

Answer 12

Keep weld reinforcement to a minimum

Question 13

Method to reduce transverse distortion

Answer 13

Use a fast deposition rate

Question 14

Disadvantage to rigid clamping and fixturing

Answer 14

Some Distortion can occur after releasing the clamping

Question 15

Advantage of a jigging device

Answer 15

It maintains accuracy of the finished product

Question 16

Pieces of metal placed on either side of the joint to absorb the heat of the Weld and help prevent Distortion are called

Answer 16

Chill strips

Question 17

Purpose of balancing bulbs around the neutral access of a worn shaft

Answer 17

To equalize the contraction stresses of the welds

Question 18

How can you help control distortion on welding light gauge metal

Answer 18

Increase the number of tacks

Question 19

Which fillet weld application produces the greatest amount of distortion

Answer 19

Multi pass fillet welds with a convex profile

Question 20

Characteristic of a good welding design

Answer 20

It uses formed or rolled sections

Question 21

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

Answer 21

weld from the center and towards the outside in both directions

Question 22

Advantage of using sub-assemblies

Answer 22

They provide more welds in the flat position
