Welding 1 - MIG Welding Exam
Questions and Answers 100% Pass
MIG - ✔✔Metal Inert Gas, also know as Gas Metal Arc welding and is the most
frequent form of welding in the modern manufacturing industry.
MIG Process - ✔✔Semi automatic process which feeds a continuous wire electrode
through a welding gun to the work. A shielding gas is given out around the wire and
weld pool to stop contamination. Electric power is transferred to the wire at contact tip.
Wire Feed - ✔✔Consisting of two rollers which rotate to feed wire through the gun.
Weld Gun - ✔✔Is designed to provide electrical pickup to the wire from the contact tip
and deliver shielding gas to protect weld metal.
Contact Tip - ✔✔Electrical contact point where wire leaves the welding gun. Needs to
be kept clean to avoid blockages.
Shielding Gas - ✔✔Keeps the arc stable and protects the molten weld from
contamination to increase weld quality. Argon gas blended with oxygen and carbon
dioxide.
Nozzle - ✔✔The outer casing to the welding gun which directs the flow of the shielding
gas.
Welding mask - ✔✔Has a dark glass lens to filter out harmful rays and allow you to see
what you are welding without causing any damage to your eyes.
