Question 1

____ are dimensioned by giving the length of their legs and their thickness.
A) Angles
B) Sheets
C) Pipes
D) Plates

Accepted Answer

Angles are dimensioned by giving the length of their legs and their thickness.

Question 2

____ is usually 3/16 in.(4.8 mm) or thicker and measured in inches and fractions of inches.
A) Plate
B) Sheet
C) Pipe
D) Tubing

Accepted Answer

Plate is usually thicker than 3/16 in. (4.8 mm) and is measured in inches and fractions of inches. Sheet is thinner than 3/16 in. and measured in gauges or decimal fractions of an inch. Pipe and tubing are measured by their outer diameter, not thickness.

Question 3

What should you do if you are going to be welding around other workers who are not welders?
A) Tell them about the sparks.
B) Tell them about the arc light.
C) Tell them of other hazards.
D) All of the above

Accepted Answer

When welding around other workers who are not welders, it is important to inform them of all possible hazards to ensure their safety. This includes informing them about the sparks, arc light, and any other potential hazards associated with the welding process. Therefore, the best choice is D, all of the above.

Question 4

____ is dimensioned by its diameter and schedule or strength.
A) Pipe
B) Angle
C) Plate
D) Sheet

Accepted Answer

Diameter and schedule or strength are specific to pipes. Angle, plate, and sheet are dimensioned by thickness, length, and width.

Question 5

A ____ line will make a long, straight line on metal and is best used on large jobs.
A) chalk
B) soapstone
C) metal scribe
D) center punch

Accepted Answer

A chalk line is used to create long, straight lines on various surfaces, including metal, and is particularly useful for large jobs where precision and visibility are required.

Question 6

____ is/are usually 3/16 in.(4.7 mm) or less and measured in gauge or decimals of an inch.
A) Sheets
B) Plates
C) Pipes
D) Tubing

Accepted Answer

Sheets are thin, flat pieces of material that are usually less than 3/16 in. thick and measured in gauge or decimals of an inch.

Question 7

Most assembly drawings are done as two, three, or more ____ views.
A) assembly
B) pictorial
C) exploded
D) orthographic

Accepted Answer

Assembly drawings are usually done as orthographic views, which show multiple sides of the object being assembled in a way that accurately represents the shape and size of each individual part. Pictorial drawings show the object as a whole and exploded drawings show the individual parts separated out, but neither of these formats provide the detailed information needed for assembly.

Question 8

____ are useful for clamping larger parts.These clamps have a sliding lower jaw that can be positioned against the part before tightening the screw-clamping end.
A) Pipe clamps
B) Cam-lock clamps
C) Bar clamps
D) C-clamps

Accepted Answer

Bar clamps are the best choice for clamping larger parts as they have a wider opening capacity and a sliding lower jaw that can be positioned against the part before tightening the screw-clamping end. Pipe clamps have a limited opening capacity, cam-lock clamps are designed for quick clamping of smaller parts, and C-clamps may not have a sliding lower jaw.

Question 9

____ are available in a range of sizes with a number of various jaw designs.Their versatility and gripping strength make them very useful.
A) Cam-lock clamps
B) Locking pliers
C) Pipe clamps
D) Specialty clamps

Accepted Answer

The description matches that of locking pliers, which are adjustable in size and have various jaw designs to provide versatility and gripping strength. Cam-lock clamps, pipe clamps, and specialty clamps may have some of these features but do not necessarily match the full description.

Question 10

At the very basic level, ____ can be just placing two pieces of metal flat on a table and tack welding them together for practice welding.
A) nesting
B) assembly
C) grinding
D) laying out

Accepted Answer

Assembly is the correct term for putting together pieces, including in the context of welding. It involves arranging and joining components, which can be as simple as placing two pieces of metal together on a table and tack welding them.

Question 11

____ sizes are always given as the outside diameter.
A) Sheet
B) Plate
C) Tubing
D) Pipe

Accepted Answer

Tubing sizes are typically given as the outside diameter, whereas pipe sizes are usually given as the nominal diameter.

Question 12

Holding the ____ slightly above the surface allows it to be struck repeatedly, making marks to form a line that is easily seen for cutting.
A) chalk
B) soapstone
C) punch
D) metal scribe

Accepted Answer

The answer of Holding the ____ slightly above the surface...

Question 13

____ clamps are specialty clamps that are often used in conjunction with a jig or a fixture.They can be preset, allowing for faster work.
A) Cam-lock
B) Specialty
C) Pipe
D) Bar

Accepted Answer

Cam-lock clamps are specialty clamps that are often used in conjunction with a jig or a fixture. They have a quick-release lever that allows for faster work and can be preset for even faster use. Pipe and bar clamps are used for larger-scale clamping, while specialty clamps can refer to a wide range of specific clamps for unique applications.

Question 14

____ have been specially designed for welding.Some of these clamps have a spatter cover over the screw, and others have their screws made of spatter-resistant materials such as copper alloys.
A) Locking pliers
B) Pipe clamps
C) C-clamps
D) Bar clamps

Accepted Answer

C-clamps have been specially designed for welding and some have a spatter cover over the screw, while others have spatter-resistant screws made of copper alloys. Locking pliers, pipe clamps, and bar clamps are not necessarily designed for welding purposes.

Question 15

As the number of parts that make up a weldment ____, the problem of compounding the errors ____.
A) increases, decreases
B) increases, stays the same
C) increases, increases
D) decreases, stays the same

Accepted Answer

As the number of parts that make up a weldment increases, the problem of compounding the errors also increases. This is because each part has its own set of potential manufacturing and fabrication errors, and when they are assembled together, those errors can compound and become more significant.

Question 16

____ clamps are very similar to bar clamps.The advantage of these clamps is that the ends can be attached to a section of standard 1/2-in.(13 mm) pipe.
A) Specialty
B) Bar
C) Cam-lock
D) Pipe

Accepted Answer

Pipe clamps are the only option mentioned that allow for attachment to standard 1/2-in.(13 mm) pipe.

Question 17

Schedule ____ for a pipe is often considered a standard strength.
A) 10
B) 40
C) 80
D) 180

Accepted Answer

Schedule 40 is often considered a standard strength for pipes. Schedule 10 is thinner and is used for lighter duty applications, while Schedule 80 and 180 are thicker and are used for heavy-duty applications requiring higher pressure ratings.

Question 18

No matter how large or complicated the welded structure, it is assembled ____ piece(s) at a time.
A) one
B) two
C) three
D) four

Accepted Answer

Welded structures are assembled one piece at a time, regardless of their size or complexity. This ensures proper alignment and fit-up of the components, and allows for proper inspection and welding of each joint before moving on to the next piece.

Question 19

If a ____ is used for marking lines, it should be sharpened properly to increase accuracy.
A) center punch
B) chalk
C) soapstone
D) metal scribe

Accepted Answer

The answer of If a ____ is used for marking...

Question 20

Only ____ type(s) of metal(s) is/are usually used in most weldments.
A) one
B) two
C) three
D) four

Accepted Answer

Only one type of metal would be typically used in weldments. Welding involves combining two or more pieces of metal into a single piece, so using multiple types of metal would defeat the purpose of creating a cohesive, strong joint.
