Question 2

____ are pieces of metal that are temporarily attached to the weldment's parts to enable them to be forced into place.Anytime these pieces of metals are used, they must be removed and the area ground smooth.
A) Hammers
B) Anvils
C) Jacks
D) Cleats or dogs

Accepted Answer

Cleats or dogs are commonly used as temporary attachments in welding to hold parts in place while welding. They can be easily attached and removed, but require grinding or sanding to smooth out the area where they were attached. Hammers, anvils, and jacks are not typically used for this purpose in welding.

Question 3

Accepted Answer

The answer of The first step in almost every welding...

Question 4

​One advantage of tools like the ____ is that all sides of a cut in structural shapes and pipe can be laid out from one side without relocating the tool.
A) ​pipe clamp
B) ​contour marker
C) ​template
D) ​metal scribe

Accepted Answer

The contour marker is designed to accurately layout cut lines on structural shapes and pipes, allowing for all sides of a cut to be marked from one side without the need to relocate the tool. This makes it a valuable tool in metal fabrication and construction.

Question 5

​What layout tool can be used to mark a straight line by dragging it along the straight edge of plate while holding a piece of soapstone against the end of the tool?
A) ​straight edge
B) ​12' tape measure
C) ​framing square
D) ​combination square

Accepted Answer

A combination square can be used to mark a straight line by dragging it along the straight edge of a plate while holding a piece of soapstone against the end of the tool.

Question 6

​What is the process of laying out parts so that the least amount of scrap is produced?
A) ​nesting
B) ​compressing
C) ​pre-packing
D) ​close packing parts

Accepted Answer

Nesting refers to the process of laying out parts in a way that minimizes the amount of material wasted or scrap generated. This is achieved by arranging the parts in such a way that they fit together closely, with minimal gaps between them. The goal is to maximize the use of the available material, while minimizing waste, scrap, and associated costs. Compressing, pre-packing, and close packing parts are not the most accurate terms for describing this process.

Question 7

​What problem might be caused if the root opening is larger than normal?
A) ​More filler metal will be needed and the heat-affected zone will be larger.
B) ​You might have to use a higher amperage setting to melt both sides of the root to get good fusion.
C) ​Using a very short arc will help solve the problem.
D) ​Nothing if you are a good welder and can fill the larger gap.

Accepted Answer

A larger root opening means there is more space to be filled with filler metal, resulting in a larger heat-affected zone. This will require more filler metal to be added to maintain proper joint strength and may also lead to distortion and a weaker weld.

Question 8

​What is the term used to describe the process of bringing together all of the parts for a weldment?
A) ​assembly
B) ​fabrication
C) ​part requisition
D) ​bill-of-materials listing

Accepted Answer

The process of bringing together all of the parts for a weldment is typically referred to as assembly. Fabrication refers to the process of constructing or building something, so it could be part of the overall process of creating a weldment, but it is not specific to the final step of bringing everything together. Part requisition and bill-of-materials listing are related to the materials and parts needed for the weldment, but not specifically the process of assembling them.

Question 9

____ will do a better job than cleats or dogs if the weldment's parts must be moved more than about 1/2 in.
A) Jacks
B) Hammers
C) Anvils
D) Abrasive grinding disks

Accepted Answer

Jacks are a better choice than cleats or dogs if the weldment's parts must be moved more than about 1/2 in. Jacks can be used to lift and move heavy weldments precisely and safely, while cleats or dogs may not provide enough clearance or control. Hammers, anvils, and abrasive grinding disks are not appropriate for moving weldment parts.

Question 10

​Which of the following would not be considered a preshaped part for an assembly?
A) ​machined
B) ​bent
C) ​bar stock
D) ​precut

Accepted Answer

Bar stock is a raw material that would need to be shaped or machined into the required part shape before assembly. Machined, bent, and precut parts have already been shaped to fit the assembly.

Question 11

____________________ is the process of assembling the parts to form a weldment.

Accepted Answer

The answer of ____________________ is the process of assembling the...

Question 12

​What tool can be used to draw a circle?
A) ​scribe
B) ​contour marker
C) ​compass
D) ​try-square

Accepted Answer

A compass is specifically designed to draw circles and arcs.

Question 13

____, such as those for pipe welding, are available for many different types of jobs.Such clamps make it possible to do faster and more accurate assembling.
A) Bar clamps
B) Pipe clamps
C) C-clamps
D) Specialty clamps

Accepted Answer

Specialty clamps are designed for specific tasks, such as pipe welding, and are used to improve the speed and accuracy of assembling.

Question 14

​What is the term use 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. It refers to a component or part that is formed by welding together a number of separate parts. A welded structure or fabrication may also be created by welding, but weldment specifically refers to the product of welding. Assembly, on the other hand, can refer to any product or part that is put together from separate components, regardless of the methods used to join them.

Question 15

​What should be a concern as a weldment becomes larger as more parts are added?
A) ​That it is well supported so it does not fall.
B) ​That it does not get too tall and the top cannot be reached by using a ladder.
C) ​That you will have to stand on part of the weldment to reach the other parts to weld them.
D) ​It may be too large to see over.

Accepted Answer

As a weldment becomes larger with more parts added, it becomes heavier and more difficult to support. It is important to ensure that it is well supported so that it does not fall or become unstable during the welding process.

Question 16

​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. It is important to have proper ventilation to prevent inhalation of harmful fumes.

Question 17

​What is the name for the space caused by most metal cutting processes that remove a small amount of metal?
A) ​scrap
B) ​kerf
C) ​cut spacing
D) ​gap

Accepted Answer

The term for the space caused by most metal cutting processes that remove a small amount of metal is called the "kerf."

Question 18

​Why might it be easy to cut the wrong line on a part laid out for cutting?
A) ​One person laid it out and another made the cut.
B) ​The light in many shops is not very bright and it is hard to see the lines to be cut.
C) ​There is no way to identify between a cut, bend, layout, and centerline when making a PAC.
D) ​Sometimes scratches on the plate might look like the layout lines of a part to be cut.

Accepted Answer

The answer of ​Why might it be easy to cut...

Question 19

​Research for welding in space dates back to the ____ with experiments done on board the U.S.Skylab.
A) ​1940s
B) ​1950s
C) ​1960s
D) ​1980s

Accepted Answer

Welding experiments were conducted onboard the U.S. Skylab space mission in the 1960s.

Question 20

​What can be done if a number of parts are made within tolerance so that the parts' overall finished size will be within its tolerance?
A) ​Make the part a little smaller so that the parts can be used.
B) ​Adjust the weld joint fitup within its tolerance to compensate for the parts' tolerance.
C) ​Change the design to allow the parts to be used so that the cost of new parts can be avoided.
D) ​Discard the parts and start the project over with new more accurately cut parts.

Accepted Answer

If the parts are made within their tolerance, adjusting the weld joint fitup within its tolerance is the best solution to compensate for the parts' tolerance. This will ensure that the final product is within the desired tolerance and can be used as intended. Making the part smaller may jeopardize the functionality of the part, changing the design may result in a longer lead time and additional cost, and discarding the parts will result in wasted resources.
