Dr. Muller Advanced Welding GMAW –
Exam Questions And Answers
active gas - - -
correct answer ✅A gas that reacts with other elements. GMAW
uses both active and inactive gas as shielding.
American Welding Society - - -
correct answer ✅The non-profit society that regulates the
industrial standards for welding and promotes the welding industry.
You can use this GMAW mode on thin materials with low current - -
-
correct answer ✅Globular transfer
amperage - - -
correct answer ✅A measurement that indicates the amount of
current flowing in a circuit, which is measured in amperes. GMAW
_____ is determined by wire speed.
This is measured in inches per minute or poundage per hour - - -
correct answer ✅wire feed or wire melting rate
argon - - -
correct answer ✅An inactive gas commonly used as shielding.

Exam Questions And Answers
_____ is much heavier than air, so it effectively shields the weld
area.
carbon dioxide - - -
correct answer ✅An active gas commonly used as shielding for
GMAW. ____ ______is inexpensive but yields a violent arc.
The _______ is the natural bend in the wire - - -
correct answer ✅cast
carbon steel - - -
correct answer ✅A steel that consists of iron and carbon, without
any additional materials.
Distance from the tube to the arc measured along the wire length is
the ___________ - - -
correct answer ✅stickout
constant voltage welder - - -
correct answer ✅A welding machine that maintains a constant

Exam Questions And Answers
spool drag - - -
correct answer ✅This is adjusted so that the reel stops when the
feed stops
Density - - -
correct answer ✅one of the most important characteristics of a
shield gas - how much heavier than air
consumable electrode - - -
correct answer ✅An electrode that conducts electricity to the arc
but also melts into the weld as a filler metal.
slope - - -
correct answer ✅voltage decrease as amperage increase
contact tip - - -
correct answer ✅The device located inside the welding gun that
conducts electricity to the electrode. The _____ ___ is usually made
of copper.
