Question 1

An extremely fast and economical welding process is ____. The welds are very clean and the process can be used with thin material or heavy plate.
A) shielded metal arc welding process
B) gas metal arc welding process
C) oxyfuel welding process
D) gas tungsten arc welding process
E) none of the above

Accepted Answer

Gas metal arc welding (GMAW) process, also known as MIG (metal inert gas) welding, is an extremely fast and economical process. The process uses a continuously-fed wire electrode and a shielding gas to protect the weld from contamination. The clean welds produced by GMAW make it suitable for use with thin material or heavy plates. Shielded metal arc welding (A), oxyfuel welding (C), and gas tungsten arc welding (D) are not as fast or economical as GMAW.

Question 2

The ____ costs less to operate than other methods.
A) shielded metal arc welding process
B) gas metal arc welding process
C) oxyfuel welding process
D) gas tungsten arc welding process
E) none of the above

Accepted Answer

The oxyfuel welding process is the least expensive welding process to operate because it uses relatively inexpensive fuel gases, such as acetylene and oxygen.

Question 3

A) bevel
B) square
C) V
D) triangular
E) none of the above

The answer of High quality welds can be made rapidly...

Question 5

When the flush contour weld symbol is applied without any consideration for how to finish it, the welder chooses which type of finishing should be done.

Accepted Answer

When the flush contour weld symbol is applied, it specifically instructs the welder to produce a weld that is flush with the surface of the base metal and has a smooth and unbroken contour. The finish of the weld should already be specified on the drawing or in the welding procedure specification (WPS). It is not up to the welder to choose which type of finishing to do as this can affect the integrity and appearance of the final product.

Question 6

A V groove weld symbol with a "3/8" to the right of the symbol, both of which are under the reference line means ____.
A) the weld depth on the arrow side should be 3/8"

C) the depth that the weld penetrates the surface should be 3/8" on the other side
D) the material that this weld is being placed on is 3/8" thick, and the weld should penetrate the entire separation

Accepted Answer

The answer of A V groove weld symbol with a...

Question 7

The ____ is created when one piece is square and the other piece has a beveled surface.
A) bevel groove weld
B) U groove weld
C) J groove weld
D) square groove weld
E) none of the above

Accepted Answer

A bevel groove weld is created when one piece is square and the other piece has a beveled surface.

Question 8

A welding symbol, which consists of two lines ending on the underside of the reference line at 90° to one another, has the notation 3/8 to the left of the two lines. What does this signify?
A) A V groove weld penetrates the other side of the surface to a depth of 3/8".
B) A fillet weld penetrates the arrow side of the surface to a depth of 3/8".
C) A bevel weld penetrates the arrow side of the surface to a depth of 3/8".
D) A V groove weld penetrates the arrow side of the surface to a depth of 3/8".
E) None of the above. This is an incorrect symbol.

Accepted Answer

The two lines ending on the underside of the reference line at 90° form a V groove, and the notation 3/8 to the left of the two lines signifies the depth of penetration on the arrow side of the surface. Therefore, the correct option is D, where a V groove weld penetrates the arrow side of the surface to a depth of 3/8".

Question 9

The size of a fillet weld is shown on the ____ side of the reference line as (to) the weld symbol and to the ____ of the symbol.
A) other; left
B) same; left
C) other; right
D) same; right
E) none of the above

Accepted Answer

The size of a fillet weld is indicated on the same side of the reference line as the weld symbol and to the left of the symbol, according to standard welding symbol notation.

Question 10

C, M, H, R, and G are letters associated with the ____.
A) standard location of elements of a welding symbol
B) flush contour weld
C) resistance spot weld
D) welding process
E) none of the above

Accepted Answer

The answer of C, M, H, R, and G are...

Question 11

The standard welding symbol, which is shaped like a right triangle with equal sides adjacent to that angle, represents a ____ weld.
A) bevel
B) square
C) V
D) triangular
E) none of the above

Accepted Answer

The standard welding symbol described does not match any of the common weld types listed (bevel, square, V, or triangular).

Question 12

The location of a weld ____.
A) depends on the type of metal material that is being used
B) is based on the type of welding process used
C) is where the materials actually combine the grain structure from one piece to the other
D) depends on the strength of the welded material
E) none of the above

Accepted Answer

The location of a weld is where the materials actually combine the grain structure from one piece to the other. It is the area where the fusion of the metal occurs, creating a strong bond between two separate pieces. The location may vary based on the type of welding process used, but ultimately it is where the two materials are joined together. The type of material and the strength of the welded material may be factors in determining the location of the weld, but they are not the primary determinants.

Question 13

The weld symbol in which a small circle is drawn with its center at the intersection of the leader line and the reference line means ____.
A) it is a field weld
B) it is a plug and slot weld
C) to weld all around
D) to spot weld
E) none of the above

Accepted Answer

The weld symbol with a small circle at the intersection of the leader line and reference line indicates a weld that is to be made all around the joint. This is also known as a circular weld or a 360-degree weld.

Question 14

A fillet weld with the notation "1/4?6?1/2" next to its graphic symbol means ____.
A) one weld leg length is 1/4" and the other weld leg length is 1/2"
B) one weld leg length is 1/4" and the other weld leg length is 1/2 that amount
C) one weld is 1/4" thick, and next weld in line is 1/2" thick
D) one weld (1/4") is on this side, and the other weld (1/2") is on the other side
E) none of the above

Accepted Answer

The notation "1/4?6?1/2" next to a fillet weld symbol indicates that one leg of the weld is 1/4" long and the other leg is 1/2" long. The number 6 is likely a reference to the angle of the fillet weld, which would be 60 degrees in this case.

A) bevel weld
B) square weld
C) V weld
D) J weld
