spot
D globular

b. short circuiting

Step-by-step explanation:

2.4.2.1 Spray transfer is a high current density process that rapidly deposits weld metal indroplets smaller than the electrode diameter.  They are propelled in a straight line from thecenter of the electrode.  A shielding gas mixture of Argon with 1% to 2% Oxygen is used forwelding mild and low alloy steel, and pure Argon or Argon-Helium mixtures are used for weld-ing aluminum, magnesium, copper, and nickel alloys.  Welding current at which spray transfer
