Abstract
Disclosed is a method for performing gas-shielded pulsed arc welding at high current densities with a flux-cored wire as an electrode wire. The pulsed arc welding is carried out by passing a pulsed current so that a pulse peak current density during a pulse peak time Tp is 400 to 950 A/mm, a pulse base current density during a pulse base time Tb is 200 A/mmor more and differs from the pulse peak current density by 200 to 400 A/mm, and an average current density is 350 to 750 A/mm. The method allows significant spatter reduction while attaining a high deposition rate.
