Manufacture of hardfaced plates

A method of manufacturing a hardfaced plate by applying a cladding to a surface of a substrate by arc welding, the method comprising moving the substrate and a continuous arc welding wire feed relative to each other in a given direction, wherein the welding wire feed is at an acute angle to that surface.

A method of manufacturing a hardfaced plate by applying a cladding to a surface of a substrate by arc welding, which method comprises forming the substrate into a cylindrical shape, rotating the so-formed cylindrical substrate about a substantially horizontal axis, and applying continuous arc welding wire feed to the surface of the rotating substrate at a level below the uppermost level of the rotating cylindrical substrate.

Apparatus for manufacturing a hardfaced plate by applying a cladding to a surface of a substrate by arc welding, the apparatus comprising means arranged to move a substrate and a continuous arc welding wire feed relative to each other and means arranged to direct the welding wire feed in a direction generally transverse to said given direction of relative movement.

Apparatus for manufacturing a hardfaced plate by applying a cladding to a surface of a substrate by arc welding, the apparatus comprising means arranged to move the substrate and a continuous arc welding wire feed relative to each other in a given direction and means arranged to direct the welding wire feed at an acute angle to the substrate surface to be clad.

Apparatus for manufacturing a hardfaced plate by applying a cladding to a surface of a substrate by arc welding, which apparatus comprises rotatable means arranged to receive thereon a substrate to be clad, means for rotating the rotatable means, and hence a substrate received thereon, about a generally horizontal axis, and means arranged to apply, in use, continuous arc welding wire feed to the surface of the rotating substrate at a level below the uppermost region of the rotating substrate surface.
