Identify the welding process that uses a non-consumable tungsten electrode to produce the weld.

• Shielded Metal Arc Welding (SMAW)

• Gas Tungsten Arc Welding (GTAW)

• Flux-Cored Arc Welding (FCAW)

• Submerged Arc Welding (SAW)

Which material property is most important to consider when selecting a filler metal for welding?

• Color

What is the primary purpose of a fillet weld in joint design?

• To join two pieces of metal at an angle

• To increase the surface area of the weld

• To create a decorative finish

• To reduce the weight of the joint

Which piece of equipment is essential for setting up a Gas Metal Arc Welding (GMAW) station?

• A tungsten electrode

• A wire feeder

• A flux-coated rod

• A foot pedal

What is the main purpose of performing a visual inspection on a weld?

• To measure the weld's electrical resistance

• To check for surface defects and ensure proper weld size

• To determine the weld's chemical composition

• To test the weld's tensile strength

Which of the following is a common defect that can occur if welding equipment is not set up correctly?

• Porosity

• Increased ductility

• Enhanced corrosion resistance

• Improved thermal conductivity

In welding joint design, what is the purpose of a groove weld?

• To join two pieces of metal edge-to-edge

• To create a temporary joint

• To enhance the aesthetic appearance of the weld

• To reduce the amount of filler material needed

Which welding process is most suitable for welding thick sections of steel?

• Oxy-Acetylene Welding (OAW)

• Gas Metal Arc Welding (GMAW)

• Submerged Arc Welding (SAW)

• Gas Tungsten Arc Welding (GTAW)

What is the role of shielding gas in Gas Metal Arc Welding (GMAW)?

• To cool the weld area

• To protect the weld from atmospheric contamination

• To increase the weld speed

• To add color to the weld
