Welding Technology Diagnostic Assessment

What is arc welding?

• A technique for joining plastics using heat and pressure.

• Arc welding is a welding process that uses an electric arc to melt and join metals.

• A process that uses gas to melt and join metals.

• A method of cutting metals using a high-temperature flame.

Name one type of arc welding.

• Plasma Arc Welding (PAW)

• Gas Metal Arc Welding (GMAW)

• Tungsten Inert Gas Welding (TIG)

• Shielded Metal Arc Welding (SMAW)

What safety gear should you wear while welding?

• Safety goggles only

• Regular clothing without any protection

• Ear protection only

• Welding helmet, gloves, protective clothing, safety boots, respirator

Why is it important to wear a welding helmet?

• To keep the head warm during cold weather.

• To improve the aesthetic appearance of the welder.

• To enhance visibility while welding.

• It is important to wear a welding helmet to protect against harmful radiation and physical injuries.

What tool is used to hold the welding electrode?

• Welding gloves

• Welding torch or electrode holder

• Welding helmet

• Welding mask

What is the purpose of a welding machine?

• To cut materials apart.

• The purpose of a welding machine is to join materials together.

• To paint surfaces effectively.

• To heat materials for decoration.

Describe the process of MIG welding.

• MIG welding uses a solid rod instead of a wire feed.

• MIG welding requires no shielding gas during the process.

• MIG welding is primarily used for cutting metal rather than joining it.

• MIG welding is a process that uses a continuous wire feed and shielding gas to create a weld.

What does TIG stand for in welding?

• Tungsten Inert Gas

• Tungsten Ion Gas

• Tungsten Inert Gasoline

• Titanium Inert Gas

What is the main advantage of arc welding?

• The main advantage of arc welding is its ability to produce strong and durable welds.

• Arc welding is primarily used for decorative purposes.

• It requires no special equipment or training.

• It is the cheapest welding method available.

In which industries is arc welding commonly used?
