Title: Pulsed direct current arc welding
Inventor: MOIER R A
IPC: B23K9/095
Filed: 1982-04-07
Granted: 1988-10-12
Abstract: Workpieces are welded together by providing a pulsed positive DC at an arc gap with the magnitude of the DC cycled between a maintenance current level and a peak current value.  The maintenance current is sufficient to maintain current flow across the arc gap but does not provide sufficient power flow to heat the workpieces to their melting temp.  The peak current provides sufficient power flow to the workpieces to heat them to melting temp. It is used for pulsed DC arc welding. esp. of Al workpieces without using a flux. and of thin wall stainless steel workpieces.
