MIG Welding
Mig Welding - Answer-Welding process in which consumable base electrode is fed into a weld joint at a
controlled rate continuous blanket of gas shields the weld zone from contamination by the atmosphere
Mig stands for - Answer-Metal Intert gas
Stick out means - Answer-Distance from the welding tip to the end of the electrode wire
whisker means - Answer-Short lengths of welding wire that feed through the root gap of a grooved joint
and extend out from the root of the weld in all direction
Purpose of shielding gas - Answer-displace air to prevent oxygen and nitrogen in the weld zone
List two types of shielding gas used in our shop - Answer-Argon co2 and co2
Three advantages of mig welding - Answer-Arc always visible to welder no slag and a minimum amount
of splatter greatly reduced distorion in guage metal
four common mig mistakes - Answer-poor apperance bad tie in whiskers suck back cold lapping
three characteristics of a good weld - Answer-Well fused throughout joint even ripple on bead slight
crown at root
