12.4 DC Pulsed Argon Arc Welding
DC Pulse TIG Current Change Waveform
Note: I1 - Arc striking current
Ip - Set peak current
Ib - Set base current
I5 - Arc stopping current
Tp - Peak width
Tb - Base width
T - Pulse period
Pulsed argon-arc welding contains all the parameters of DC argon arc welding and only the parameters of the
setting segment are different. In addition, there are four unique adjustable parameters, which are described
below in combination with the figure.
●
Peak current (Ip): Adjusted according to process requirements.
●
Base current (Ib): Adjusted according to process requirements.
●
Pulse frequency (1/T): T=Tp+Tb, adjusted according to process requirements.
●
Duty cycle (100%*tp/T): The duty cycle is the percentage of the peak current duration in the pulse period, and
is adjusted according to the process requirements.
