Question 1

Weld-all-around symbol is attached to the reference line at the junction of the leader when a welded connection must be performed all around a feature.

Accepted Answer

The statement is true. The Weld-all-around symbol is indeed attached to the reference line at the junction of the leader when a welded connection must be performed all around a feature.

Question 2

Welding is a process of joining any two or more pieces of metal by heating the material to a temperature high enough to cause softening or melting.

Accepted Answer

Welding involves heating the metal to a temperature high enough to cause softening or melting, so that the two pieces of metal can be fused together.

Question 3

The three types of welding tests are destructive, nondestructive, and passive.

Accepted Answer

The three types of welding tests are actually destructive, nondestructive, and mechanical/passive.

Question 4

Weld length is the length of a weld that is not continuous.

Accepted Answer

Weld length refers to the length of a weld that is not continuous, so it is true that weld length is the length of a weld that is not continuous.

Question 5

"Weldment" is another term for welding assemblies.

Accepted Answer

True, "weldment" refers to a collection of parts that are joined together by welding.

Question 6

Welding sizes are given in either inches or centimeters.

Accepted Answer

Welding sizes are typically given in inches or millimeters, not centimeters, especially in technical specifications and standards.

Question 7

Oxygen gas welding can only be performed with natural gas fuel.

Accepted Answer

Oxygen gas welding can be performed with various fuel gases, not just natural gas. Other fuel gases include acetylene, propane, and hydrogen.

Question 8

Weld symbol indicates the type of weld and is part of the welding symbol.

Accepted Answer

The weld symbol on a drawing represents the type of weld required, and it is a part of the overall welding symbol. Weld symbols convey important information about the type of weld, its size and location, and other relevant details to welders and other professionals involved in fabrication and construction tasks.

Question 9

All joints have an "arrow" side and an "other" side.

Accepted Answer

True. This is because most joints move in a specific direction and the arrow represents the direction of movement. The other side may also have specific features or limitations, but it is not necessarily designated as the "other" side.

Question 10

Weld tolerance can also be applied to a welding symbol tail by placing the tolerance value and a note giving a reference to the weld feature where the tolerance is applied.

Accepted Answer

This statement is true. Weld tolerance can indeed be applied to a welding symbol tail by placing the tolerance value along with a note that refers to the weld feature where the tolerance is applicable. This helps to specify the maximum acceptable deviation from the specified weld dimensions or other features.

Question 11

The gas tungsten arc welding process is sometimes referred to as TIG welding.

Accepted Answer

TIG stands for Tungsten Inert Gas, which is another name for the gas tungsten arc welding process.

Question 12

The side of the joint to which the arrow points is the arrow side.

Accepted Answer

The statement is true. When indicating the direction of a joint movement, the arrow points towards the side that moves, and that side is referred to as the arrow side.

Question 13

Solder is an alloy of tin and metal.

Accepted Answer

Solder is typically an alloy of tin and lead or tin and silver, but may also contain other metals such as copper or bismuth.

Question 14

The components of a welding symbol, the reference line, the leader, and the tail, must always be used.

Accepted Answer

The reference line and the arrow or leader are always required in a welding symbol, but the tail may not always be necessary depending on the specific weld being represented.

Question 15

Oxyfuel welding is faster and cleaner than other welding processes.

Accepted Answer

This statement is not true. Oxyfuel welding is actually considered a slower and less clean welding process compared to other options such as MIG or TIG welding. Oxyfuel welding involves the use of a fuel gas (such as acetylene) and oxygen to create a flame hot enough to melt and join metal parts together. However, it can produce more slag and smoke, and requires careful equipment setup and safety precautions.

Question 16

Gas tungsten arc welding is generally limited to thin materials, high integrity joints, or small parts.

Accepted Answer

Gas tungsten arc welding (GTAW), also known as TIG welding, is particularly suited for welding thin materials, creating high integrity joints, and working on small parts due to its precise heat control and the ability to produce clean, high-quality welds.

Question 17

Oxyfuel welding is most typically used to fasten larger pieces of metals together.

Accepted Answer

Oxyfuel welding is primarily used for cutting and joining medium to small thickness metals, rather than for fastening larger pieces together, which might require different welding techniques or methods.

Question 18

When single groove and symmetrical double groove welds penetrate completely through the parts being joined, the weld size can be omitted.

Accepted Answer

When single groove and symmetrical double groove welds penetrate completely through the parts being joined, the weld size can be omitted from the drawing or specifications. This is because the size of the weld is already specified by the depth of penetration.

Question 19

The type of weld is associated with the weld shape and/or they type of groove to which the weld is applied.

Accepted Answer

The type of weld is indeed associated with the weld shape and/or the type of groove to which the weld is applied.

Question 20

Welding is a more permanent fastening application than screw threads or pins.

Accepted Answer

Welding involves fusing two pieces of material together through heat and often results in a stronger and more permanent bond compared to screws or pins, which can loosen or break under stress.
