MIG Welding Concepts and Terminology

What is the correct name for 'MIG pliers'?

• MIG welding pliers

• Needle-nose pliers

• Slip-joint pliers

• Lineman's pliers

What is the main advantage of using a spool gun for aluminum welding in MIG?

• It reduces the risk of wire tangling.

• It eliminates the need for shielding gas.

• It allows for higher welding speeds.

• It provides better arc stability.

Which of the following is a common issue when using a worn-out contact tip in MIG welding?

• Reduced welding speed

• Increased wire feed speed

• Unstable arc and poor electrical contact

• Excessive gas flow

G.M.A.W. is not typically shown in amps but shown in what 2 types of readings?

• Voltage and Wire Feed Speed

• Current and Resistance

• Temperature and Pressure

• Frequency and Amplitude

What does the term G.M.A.W. mean?

• G.M.A.W. stands for Gas Metal Arc Welding.

• G.M.A.W. stands for Gas Metal Arc Wire.

• G.M.A.W. stands for General Metal Arc Welding.

• G.M.A.W. stands for Gas Manual Arc Welding.

Which of the following is a common defect in F.C.A.W. welding?

• Incomplete penetration

• All of the above

• Excessive spatter

• Porosity

The biggest difference between G.M.A.W. and F.C.A.W. is:

• G.M.A.W. uses a solid wire electrode, while F.C.A.W. uses a tubular wire filled with flux.

• G.M.A.W. is used for welding thin materials, while F.C.A.W. is used for thick materials.

• G.M.A.W. requires a shielding gas, while F.C.A.W. does not.

• G.M.A.W. is more suitable for outdoor welding, while F.C.A.W. is not.

What are the correct polarity settings for the G.M.A.W. process?

• DC Electrode Positive (DCEP)

• DC Electrode Negative (DCEN)

• AC

• DC Straight Polarity

What do you do if you stick the MIG wire to your contact tip?

• Pull the wire out and trim it

• Replace the contact tip

• Increase the wire feed speed

• Turn off the welder and let it cool

Which of the following is a common cause of porosity in F.C.A.W. welding?

• Contaminated base metal

• Improper electrode angle

• Excessive heat input

• Incorrect wire feed speed
