Inert gases such as argon or helium, or reactive gases such as CO2, which are directed under pressure into a weld zone to protect it from atmospheric contamination.
- A.
Shielding gases
- B.
Toxic hazards
- C.
Contaminants
- D.
Reactive
Correct Answer
A. Shielding gasesExplanation
Shielding gases, such as inert gases like argon or helium, or reactive gases like CO2, are used in welding to protect the weld zone from atmospheric contamination. These gases are directed under pressure into the weld zone, creating a barrier that prevents oxygen and other contaminants from coming into contact with the molten metal. By shielding the weld zone, these gases ensure a clean and strong weld.Rate this question:

- B.
Metal Inert Gas (MIG)
- C.
Gas Metal Arc Welding (GMAW)
- D.
Semiautomatic
Correct Answer
B. Metal Inert Gas (MIG)Explanation
The correct answer is Metal Inert Gas (MIG). This term is still used in reference to Gas Metal Arc Welding (GMAW), which is a type of welding process that uses a consumable wire electrode and an inert gas to protect the weld from atmospheric contamination. MIG welding is a popular and widely used method in the welding industry.Rate this question:

That which can be used up; a way of defining electrode wires used in GMAW.
- A.
Consumable
- B.
Deposition
- C.
NEMA
- D.
Automatic
Correct Answer
B. DepositionExplanation
Deposition refers to the process of adding material onto a surface, usually through a chemical or physical reaction. In the context of electrode wires used in GMAW (Gas Metal Arc Welding), deposition refers to the act of adding the wire to the weld pool to create the desired weld joint. The electrode wire is consumed during this process as it is melted and deposited onto the workpiece. Therefore, "consumable" is the correct term to describe electrode wires used in GMAW.Rate this question:

A GMAW process in which the welding current is continuous in a programmed application; the workpiece travels under a welding head or the welding head travels along the workpiece.
- A.
Deposition
- B.
Automatic
- C.
Semiautomatic
- D.
Gas Metal Arc Welding (GMAW)
Correct Answer
B. AutomaticExplanation
Automatic gas metal arc welding (GMAW) is a process where the welding current is continuous and controlled in a programmed application. In this process, either the workpiece travels under a welding head or the welding head travels along the workpiece. This automation allows for precise and consistent welding, reducing the need for manual intervention. Automatic GMAW is commonly used in industries where high production rates and quality welds are required.Rate this question:

The weight of filler metal placed onto or into a weld in a given period of time.
- A.
NEMA
- B.
Metal Inert Gas (MIG)
- C.
Deposition
- D.
Consumable
Correct Answer
C. DepositionExplanation
Deposition refers to the weight of filler metal that is added to a weld in a specific time period. It is the process of adding material to the weld joint to create a strong and durable bond. This can be done using various welding techniques, such as Metal Inert Gas (MIG) welding, where a consumable wire electrode is melted and deposited onto the weld joint. Deposition is an important factor in determining the quality and strength of a weld, as it affects the overall integrity and structure of the joint.Rate this question:

An arc welding process that produces coalescence of metals by heating them with an arc between a continuous filler metal electrode and a workpiece; shielding comes entirely from an ecternally supplied gas.
- A.
Gas Metal Arc Welding (GMAW)
- B.
Metal Inert Gas (MIG)
- C.
Reactive
- D.
Consumable
Correct Answer
A. Gas Metal Arc Welding (GMAW)Explanation
Gas Metal Arc Welding (GMAW) is the correct answer because it is a welding process that uses an arc between a continuous filler metal electrode and a workpiece to produce coalescence of metals. In GMAW, the shielding is provided entirely by an externally supplied gas, which protects the weld pool from atmospheric contamination. This process is also commonly known as Metal Inert Gas (MIG) welding. The terms "Reactive" and "Consumable" are not relevant to the given description.Rate this question:

An element that has no active properties.
- A.
Inert
- B.
Reactive
- C.
NEMA
- D.
Toxic hazards
Correct Answer
A. InertExplanation
An element that has no active properties is referred to as inert. This means that it does not easily react or interact with other substances. Inert elements are often stable and do not readily undergo chemical reactions. They are commonly used in various applications where stability and lack of reactivity are desired, such as inert gases used in lighting or in chemical reactions where a stable environment is required.Rate this question:

D. NEMAExplanation
NEMA stands for National Electrical Manufacturer's Association. It is an organization that represents manufacturers of electrical equipment and medical imaging technologies. NEMA develops standards and guidelines for the electrical industry, promotes safety and efficiency in electrical products, and provides a platform for collaboration and networking among industry professionals. This answer is correct because NEMA is the only option in the list that matches the given acronym.Rate this question:

A reduction of oxygen in the breathing zone around a welding activity caused by any arc or flame.
- A.
Reactive
- B.
Inert
- C.
Toxic hazards
- D.
Oxygen displacement
Correct Answer
D. Oxygen displacementExplanation
Oxygen displacement refers to the reduction of oxygen in the breathing zone around a welding activity caused by any arc or flame. This can be hazardous as it can lead to a lack of oxygen for the welder or anyone in the vicinity, potentially causing asphyxiation or other health issues.Rate this question:

- D.
Shielding gases
Correct Answer
B. Toxic hazardsExplanation
The given answer, "Toxic hazards," accurately explains the concept of poisonous gases, fumes, and vapors produced during certain welding processes. These substances can contaminate the air and pose a risk to the health and safety of individuals involved in welding. Therefore, it is crucial to be aware of and take appropriate precautions to mitigate these toxic hazards. The answer effectively summarizes this concept without the need for additional information.Rate this question:

A GMAW process in which the welding current is completed as an operator squeeezes a gun trigger.
- A.
Automatic
- B.
Semiautomatic
- C.
Manual
Correct Answer
B. SemiautomaticExplanation
The correct answer is "Semiautomatic". In semiautomatic GMAW (Gas Metal Arc Welding) process, the welding current is completed as an operator squeezes a gun trigger. This means that the operator has control over initiating the welding current by squeezing the trigger, but the actual welding process is automated. This allows for a combination of manual control and automation, providing greater precision and efficiency in the welding process.Rate this question:
