Welding Print Reading exam questions and answers

The main purpose of drawings in the welding industry is to communicate ideas in graphic or picture form Drawings today are usually created using CAD techniques A type of computer output device that works based on electrostatic principles is the laser printer Which type of drawing can be used to test prototypes and assemblies? CAD drawing Which of the following are not included on a welding print? photographs Another term for xerography is electrostatic process The electrostatic process relies on the principles that opposite charges attract and like charges repel Which reproduction process consists of making a tracing, developing and fixing a print, and then washing and drying the print? Blueprint process Which type of computer output device mimics the motion that a human hand might make while drawing? Pen plotter Which reproduction technique was originally developed to reduce the storage needed for original drawings? Microfilm process Another term for a print of an original drawing is Reproduction The lines and figures that have specific meanings in welding drawings to accurately describe the shape, size, material, finish, and fabrication of an object are symbols Even though the actual process is not used much anymore, the term _______ is commonly used to refer to prints made by any process blue print A machining system that uses information from CAD drawings to produce parts and assemblies is a _______ system CAM An inexpensive computer output device that may be small enough to fit on a desktop is a _______ printer inkjet Print created from a microfilm negative Blow-back Reproduction technique that uses an electrostatic charge to duplicate an original Xerography General term for a duplicate of an original drawing Print Reproduction on which dark lines are printed on a white background White print Lines and figures that have specific meanings on a drawing Symbols To convert a common fraction to a decimal fraction, you would divide the numerator by the denominator A metric rule is graduated in millimeters The decimal fraction equivalent of 3/4 inch is .75 One millimeter is equal to ______ of a meter 1/1000 When no number can be divided evenly into both the numerator and the denominator of a fraction, the fraction is said to be in lowest terms Which of the following equations would convert 3.25 inches to millimeters? 3.25 x 25.4 Which of the following equations would convert 7.5 inches to feet? 7.5 divide 12 A decimal rule has ______ divisions on one edge, and either 50 to 100 divisions on the other edge 10 A number that will divide evenly into both the numerator and the denominator a fraction is a ______ Common factor The marks or divisions on the edge of a rule are called graduations A welding drawing that contains both inch units and metric units is said to be ______ dual dimensioned In a drawing that contains both inch and millimeter dimensions, the inch dimension is placed above or to the left of the millimeter dimension in the ______ method position Millimeters are placed in brackets when the ______ method is used in the United States bracket The item on a dual dimensioned drawing that shows how the inch and millimeter dimensions can be identified is a ______ note A decimal number that expresses less than a whole number is a decimal ______ fraction Rule marked in millimeters Metric rule Marks or divisions on the edge of a rule Graduations Encloses the metric dimension in square brackets in a US dual dimensioned drawing Bracket method Measuring the straight-line distance between two points linear measure Displays the inch dimension above or to the left of the millimeter dimension in a US dual dimensioned drawing Position method Rule marked in decimal inches Decimal rule No common factor exists for the numerator and denominator of a fraction Lowest terms Number being divided to convert a common fraction to a decimal fraction Dividend Center lines have long dashes altering with two short dashes False The symbol for cast iron is also used for general-purpose section lines True Extension lines indicate the termination of a dimension True A dimension line with an arrowhead at only one end is known as a break line False The type of line used to show visible edges and contours of an object is a ______ line visible Internal features of an object are shown using ______ lines hidden One of the purposes of a ______ line is to show where the dimension terminates extension The centers of holes, weld plugs, and round parts are shown on prints using ______ lines section The heavy line labeled with letters at both ends that is used to show the direction from which a sectional view is taken is a ______ line cutting plane A drawing that is scaled at one-half the size of the actual part is indicated by ______ in the title block 1:2 Another name for a routing sheet is shop traveler The views and features shown on a print combine to describe the ______ of an object Shape "AISI 1020 steel" is an example of a material specification Which of the following is not a physical change caused by heat treating a metal or alloy? planting Which of the following is a standard size B print 11 x 17 inches The purpose of annealing a metal is to make them easier to work
