Coating system and method for e-coating and degasification of e-coat fluid during e-coat

A method for electrocoating a metal part, comprising:

• immersing a metal part in an electrocoating fluid solution positioned in an electrocoating tank, wherein the electrocoating fluid solution comprises dissolved gases;
• directing a plurality of omnidirectional acoustic waves at an ultrasonic frequency uniformly throughout a volume of the electrocoating fluid solution in a zone of the electrocoating tank, wherein the directed plurality of omnidirectional acoustic waves generate cyclic positive and negative pressure waves that cause a controlled degasification of the dissolved gases from the volume of the electrocoating fluid solution that corresponds to the zone, wherein the plurality of omnidirectional acoustic waves are directed through a plurality of ultrasonic transducers positioned in the zone of the electrocoating tank, wherein the plurality of ultrasonic transducers comprises a first plurality of ultrasonic transducers located in a first region of the zone and a second plurality of ultrasonic transducers located in a second region of the zone, wherein the first region is spaced apart from the second region, and wherein the first plurality of ultrasonic transducers are staggered from or aligned with the second plurality of ultrasonic transducers;
• and
• controlling a first intensity of the directed plurality of omnidirectional acoustic waves over a defined time period to accelerate or promote dispersion of an electrocoating pigment and thereby control deposition of the electrocoating pigment over the metal part immersed in the electrocoating fluid solution.
