Define and describe the GMAW process in detail: - - -
correct answer ✅GMAW Process: An arc welding process that uses
an arc between a continuous filler metal electrode and the weld
pool. The process is used with shielding gas from an externally
supplied source.
The gas metal arc welding process is also known as:
a) MIG welding.
b) flux cored arc welding.
c) self-shielding process.
d) shielded metal arc welding. - - -
correct answer ✅The gas metal arc welding process is also known
as:
a) MIG welding.

What is meant by mode of metal transfer? - - -
correct answer ✅What is meant by mode of metal transfer?
The way that the weld metal transfers across the arc from the end
of the electrode to the weld zone. (Spray transfer, globular and
short circuiting.)
Spray transfer employs higher:
a) inductance settings.
b) voltage settings.
c) reactance settings.
