Answer 2

True

Question 3

____ welding or brazing is best suited to large-volume production runs because of the expense involved in special jigs and fixtures.

A) Machine
B) Manual
C) Automatic
D) Semiautomatic

Answer 3

C

Question 4

A(n) ____ joining process is one that is completely performed by hand.

A) semiautomatic
B) manual
C) machine
D) automatic

Question 5

In shielded metal arc welding the electrode holder starts at a distance of ____ in. from the work.

A) 4
B) 6
C) 14
D) 20

Question 6

The most commonly used semiautomatic (SA) arc welding processes are gas metal arc welding (GMAW) and ____.

A) oxyacetylene welding (OAW)
B) torch brazing (TB)
C) flux cored arc welding (FCAW)
D) shielded metal arc welding (SMAW)

Question 7

In the GMAW process, the electrode holder must be lowered steadily as the weld progresses to feed the electrode and maintain the correct arc length.

Question 8

Fewer weld craters occur in continuous welding and it is much faster.

Question 9

A(n) ____ joining process is one in which the welding is performed by equipment and you control the welding progress by making adjustments as required.

A) machine
B) manual
C) automatic
D) semiautomatic

Question 10

SMA electrodes cannot be used completely as they have a waste stub of approximately ____ in.

A) 1
B) 2
C) 3
D) 4

Question 11

In a semiautomatic joining process, the filler metal is being fed from a large spool, so you do not have to stop welding to change filler electrodes or filler metal.

Question 12

The arc welding light should be accessible to all work areas.

Question 13

A(n) ____ joining process is a dedicated process (designed to do only one type of welding on a specific part) that does not require you to make adjustments during the actual welding cycle.

A) manual
B) machine
C) semiautomatic
D) automatic

Question 14

The most commonly used manual arc (MA) welding process is ____.

A) flux cored arc welding (FCAW)
B) submerged arc welding (SAW)
C) gas metal arc welding (GMAW)
D) shielded metal arc welding (SMAW)

Question 15

In a manual joining process, the placement or location of the weld bead within the weld joint affects the reinforcement, width, and appearance of the weld.

Question 16

A(n) ____ joining process is one in which the filler metal is fed into the weld automatically.

A) semiautomatic
B) automatic
C) manual
D) machine

Question 17

In a manual joining process, the rate of travel or speed at which the weld progresses along the joint affects the width, reinforcement, and penetration of the weld.

Question 18

The addition of filler metal to the weld by an automatic wire-feeder system enables you to increase the uniformity of welds, productivity, and weld quality.

Question 19

____ equipment is often dedicated to one type of product or part.

A) Semiautomatic
B) Machine
C) Automatic
D) Automated

Question 20

In a manual joining process, the rate at which filler metal is added to the weld affects the strength, appearance, and possible acceptance of the joint.

Question 21

The Robot Institute of America states that a(n) ____________________ robot is a "reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks."

Question 22

____________________ should be mounted around the floor and work area to stop all movement when unauthorized personnel are detected in the work area during the operation.

Question 23

The first industrial robots were ____________________ robots that were used to move material with little repetitive accuracy required.

Question 24

Most robots can perform movements in three basic directions: longitudinal (X), transverse (Y), and ____________________.

Question 25

____________________ joining processes are similar to automatic joining except that they are flexible and more easily adjusted or changed.
