MIG Welding Test
Name two advantages of wire welding over arc welding. - Answer-Can Weld on thinner metal
Easy to use (Push a button) (Electrode continuously flows)
What type of metal transfer will be using in the shop? - Answer-Short-Circuit Metal Transfer
List 3 advantages of using short circuit metal transfer. - Answer-Used in all positions
Less heat required
Easier to use
What is the purpose of the gas in MIG welding? - Answer-To protect molten metal from elements in the
air during welding
What two common gases are used in MIG welding? - Answer-Argon
Carbon Dioxide
Explain the difference between the electrode for Arc Welding and the electrode in MIG welding. -
Answer-Arc Welding uses a rod that needs to be changed and you have to move closer to metal as you
weld while MIG welding uses an electrode that uses a wire that continuously flows allowing you to keep
the same distance.
