  • Hybrid electroslag cladding
    Patent number: 10766100
    Abstract: A hybrid electroslag cladding method includes the steps of: providing a workpiece (6) to be cladded; guiding a strip electrode (4) onto the surface of the workpiece (6); cladding the strip electrode (4) onto the surface of the workpiece (6) using electroslag cladding; guiding a metal cored hybrid electroslag cladding wire (7) into the weld puddle (9) of the strip electrode (4) for controlling the chemical composition of the cladding.
    Type: Grant
    Filed: November 26, 2015
    Date of Patent: September 8, 2020
    Assignee: Lincoln Global, Inc.
