Exam 25: Welding Automation and Robotics

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

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

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

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

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.

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."

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

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.

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.

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

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

Automation has allowed manufacturers to increase productivity and cut costs, which makes their products more competitively priced.

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

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

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.

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.

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.

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

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

____________________ 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.
