PULSE MIG
The Pulsed MIG process works by forming one droplet of molten metal at the end of the electrode per pulse. Then, just the right amount of current is added to push that one droplet across the arc and into the puddle. The transfer of these droplets occurs through the arc, one droplet per pulse.
Advantage:
- Absent or very low levels of spatter.
- More resistant to lack of fusion defects than other modes of GMAW metal transfer.
- Excellent weld bead appearance.
- Reduced levels of heat induced distortion.
- Ability to weld out-of-position.
- Lower hydrogen deposit.
- Reduces the tendency for arc blow.
- Lends itself to robotic and hard automation applications.
DOUBLE PULSE MIG
Using Waveform Control Technology, the welding machine alternates between high and low energy pulses. This combination of high and low pulses produces the "rippled" bead appearance. The high energy pulses provide a hotter arc (longer arc duration), which improves cleaning action at the base material. The low energy pulses allow the weld puddle to cool, which controls the heat input for good penetration.
Advantage:
- Minimal distortion, even when gap conditions and wire placement vary.
- Outstanding control of arc characteristics, making it easier to produce excellent welds.
- Rippled bead appearance requires no weaving to produce a uniform bead.
- Controls the arc length and heat input together for excellent penetration profile.
- Controls the arc heat, making it ideal for welding thinner materials.
