GMAW welding can be performed as: - - -
correct answer ✅semiautomatic
machine
automatic
most commonly used in semiautomatic welding
GMAW-S, Short Circuiting Transfer - - -
correct answer ✅Low currents allow the liquid metal at the
electrode tip to be transferred by direct contact with the molten
weld pool. This process requires close interaction between the wire
feeder and the power supply.
Most common on:
Thin or properly prepared thick sections of material.
On a combination of thick to thin materials.

With a Wide Range of Shielding Gases.
Globular Spray Metal Transfer - - -
correct answer ✅Used on thin materials and at a very low current
range.
The arc melts the end of the electrode, forming a molten ball of
metal. The ball eventually falls across the arc, landing in the molten
weld pool. This process is rarely used by itself.
Axial Spray Method - - -
correct answer ✅Pointing the wire tip from which very small drops
are projected axially across the arc gap to the molten weld pool.
There are hundreds of drops her second crossing from the wire to
the base metal. The drops are propelled by arc forces at high
velocity in the direction the wire is pointing.. Welding in vertical
and overhead positions is possible without losing control of
transfer.

to occur? - - -
correct answer ✅• Argon Shielding (or argon rich shielding gas
mixtures)
