Pulsed MIG Welding MIG welding method Welding Wiresis the use of pulse current instead of the usual pulsating DC.
As a result of the pulse current, pulse MIG welding arc pulse, with the usual continuous current (pulsating DC) welding:
1, the welding parameters wider range of adjustment;
If the peak current is greater than I0 is the critical current I0 is the average current is less than the jet transition, as long as the pulse, you can still get spray transfer.
2, can be convenient, precise control of the arc energy;
Not only the pulse base value current size is adjustable, and the duration of 10-2 S-conditioning unit.
3, sheet and position, backing weld ability is superior.
Bath only at the time of pulse current, melting, cooling and crystallization can be obtained in the current time base value. Compared with continuous current welding, the penetration and the same premise, Mig Welding Electrodethe average current (weld heat input).
