PULSE WAVE SHAPING PRINCIPLES

WAVE DESIGNER
Contents Description
How the pulse waveform transfers weld droplets to the
weld surface
How WFS and primary wave shape parameters effect
welding
Flowchart and step by step descriptions of the pulse
wave design process
How peak current, peak time, frequency, and
background current effect weld droplet transfer
How ramp up rate, % ramp overshoot, tailout speed,
tailout time, stepoff amperage, and background time
effect weld droplet transfer
Sample development of a power wave welding program
