Weld Process
MIG – Pulsed Current Welding (Pulse)
Pulse Welding (GMAW-P):
This is a GMAW process variation in which the welding current is pulsed resulting in a lower heat input for a given set of welding parameters when
compared to conventional GMAW.
– Disadvantages include: Special power source required to support pulsing current - Higher argon percentages required to support arc –
diameter of spatter balls typically larger than conventional GMAW spatter ball size
– Advantages include: High deposition rates - Lower heat inputs - Viable solution to many welding situations - Less spatter when compared to
conventional GMAW – Good weld appearance
Note Concerning Synergic Welding:
Synergic is a term used to describe “single dial” manipulation of multiple welding parameters at the same time.
– Disadvantages include: Specific power source designed to allow single dial manipulation of multiple welding parameters at the same time
– Advantages include: Reduced parameter development time due to the ability to change multiple parameters with a single dial turn (current and
voltage with single dial)
