mig welding process provides many advantages in manual and automatic metal joining
for both low and high
production applications. Its combined advantages when compared to covered (stick)
arc, and tig are: 1) Welding
can be done in all positions. 2) No
slag removal required. 3) High
weld metal deposition rate. 4) Overall
times for weld completion about 1/2 that of covered electrode.
5) High welding speeds.
Less distortion of the workpiece. 6) High
weld quality. 7) Large
gaps filled or bridged easily, making certain kinds of repair welding more efficient.
8) No stub loss as
with covered electrode.
