A) locking pliers
B) pipe clamps
C) C-clamps
D) bar clamps

Accepted Answer

The sentence is referring to clamps, and specifically mentions C-clamps as having a potential spatter cover or resistant screw material. The other types of clamps listed (locking pliers, pipe clamps, and bar clamps) are not mentioned in relation to spatter resistance.

Question 6

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 in a weldment increases, there are more opportunities for errors to occur in each individual part, which compounds the overall error in the welded assembly. Therefore, the problem of compounding the errors increases as the number of parts increases.

Question 7

____ 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 typically thinner than plates, pipes, and tubing and are usually measured in gauge or decimals of an inch.

Question 8

When would a portable fan be needed?
A) Anytime you are welding outside of a welding shop.
B) When the shop ventilation is not enough to blow away the welding fumes.
C) When you are welding around others to blow away the extra heat.
D) When you are making a GTA weld on thick stainless steel piping.

Accepted Answer

A portable fan would be needed when the shop ventilation is not enough to blow away the welding fumes. This is the only option that specifically mentions the need for additional ventilation. The other options mention welding in specific situations but do not necessarily indicate a need for a portable fan.

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

Locking pliers, also known as Vise-grips, are available in a range of sizes with various jaw designs. They can be used for a variety of tasks and have a strong and secure grip.

Question 10

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

It is important to inform other workers who are not welders about the hazards involved in welding, including sparks and arc light. This will help to prevent accidents and ensure everyone's safety.

Question 11

____ 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

Plates are typically thicker than both sheets and tubing, and are measured in inches and fractions of inches. Sheets are usually thinner than plates and are measured in gauge or thickness. Pipes and tubing are measured by their diameter and thickness.

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

A punch is a tool used to make indentations or marks on a surface, which can guide cutting or drilling.

Question 13

____ are useful for clamping larger parts and 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 designed with a sliding lower jaw that can be adjusted and positioned against larger parts before tightening the screw-clamping end. This makes them useful for larger projects where stability and ease of use are important. Pipe clamps are better suited for cylindrical parts, cam-lock clamps are meant for quick and easy adjustments, and C-clamps typically do not have a sliding lower jaw for positioning.

Question 14

What is the term used to identify anything that was created primarily by welding?
A) Fabrication
B) Welded structure
C) Weldment
D) Assembly

Accepted Answer

Weldment is the term used to identify anything that was created primarily by welding. Fabrication, assembly, and welded structure all can involve other methods of joining besides welding.

Question 15

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 16

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. The schedule number refers to the thickness of the pipe's walls, and schedule 40 is a medium thickness that can handle a variety of applications without being too heavy or too thin. Schedule 10 is thinner and generally used for lower pressure applications, while schedules 80 and 180 are thicker and used for higher pressure applications.

Question 17

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

Accepted Answer

Assembly drawings are typically done as orthographic views, which show the object from multiple angles or planes (front, top, side, etc.). Pictorial views show a more realistic representation of the object, while exploded views show how the components fit together but may not provide as much detail.

Question 18

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.
