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.
Claims12
A hybrid electroslag cladding method, the method comprising:
- providing a workpiece to be cladded;
- guiding a strip electrode onto a surface of the workpiece;
- cladding the strip electrode onto the surface of the workpiece using electroslag cladding;
- and
- guiding a metal cored hybrid electroslag cladding wire into a weld puddle of the strip electrode for controlling a chemical composition of the cladding, and
- for a second workpiece requiring stainless steel cladding with a different cladding composition than the workpiece, selecting a second metal cored hybrid electroslag cladding wire for controlling a chemical composition of the cladding of the second workpiece,
- wherein the chemical composition of the metal cored hybrid electroslag cladding wire differs from the chemical composition of the second metal cored hybrid electroslag cladding wire.
A hybrid electroslag cladding system, comprising:
- a cladding head for guiding a strip electrode onto a surface of a workpiece to be cladded with the strip electrode;
- a cladding power supply for providing power to the strip electrode for arcless deposition onto the surface of the workpiece;
- and
- a flux feeder for at least one of depositing flux on the strip electrode and depositing flux adjacent the strip electrode,
- wherein the cladding head is configured to guide a metal cored hybrid electroslag cladding wire into a weld puddle of the strip electrode,
- wherein the metal cored hybrid electroslag cladding wire has a composition that is defined by one of WIRE 625, WIRE 600, WIRE 825, WIRE 400, WIRE 308L, WIRE 347, WIRE 316L, or WIRE 317L, and
- wherein the hybrid electroslag cladding system further comprises a steering magnet disposed adjacent the strip electrode for steering the weld puddle magnetically.
