Definitions

  • the present invention relates to metal plates overlaid with cladding. More particularly, the present invention relates to an improved wear resistant cladding deposited by continuous bead welding.
  • cladding to the surface of metals is well known in the art.
  • a clad layer is bonded to the surface of a metal plate to produce a composite material having superior wear resistance and durability.
  • One method of applying cladding is through continuous bead welding wherein a continuous line of beads is arc welded from welding wire in adjacent straight lines along the length of the substrate plate.
  • interstices formed between the lines of bead welding are receptive to "channel wear" under highly abrasive conditions. Channel wear occurs when abrasive particles move through the interstices and slowly wear away the cladding. As the channel enlarges, the channel wear increases until the cladding is eventually compromised and the underlying metal plate exposed.
  • a clad plate comprising an improved wear resistant cladding.
  • the clad plate comprises a substrate plate having a plurality of adjacent lines of continuous bead welding deposited thereon via arc welding.
  • the bead welding is deposited in a wave-like fashion to form a sinusoidal or herringbone pattern.
  • the bead welding can be deposited to form a cladding comprising a single layer or a cladding comprising multiple layers.
  • the wave pattern of the clad layer substantially improves wear resistance of the clad plate and reduces the problem of channel wear brought about by exposure to highly abrasive environments because the abrasive materials cannot be carried continuously within the interstices between the bead welding lines as the abrasive materials flow across the clad plate.
  • the clad plate shows greatest wear resistance when used in a manner such that the abrasive materials being handled by the clad plate move across the cladding perpendicular to the direction of bead welding line deposition.
  • FIG. 1 is a top plan view of a clad plate having continuous lines of bead welding deposited on the base plate in a sinusoidal pattern.
  • FIG. 2 is a top plan view of the clad plate having continuous lines of bead welding deposited on the base plate in a herringbone pattern.
  • FIG. 3 is an end view of the clad plate wherein the cladding comprises multiple layers of bead welding.
  • FIG. 4 is an end view of the clad plate wherein the cladding comprises multiple layers of bead welding and the individual bead welding lines are shifted relative to the underlying lines.
  • FIG. 5 is an end view of the welding machine and the support frame with the base plate thereon.
  • FIG. 6 is a side view of the welding machine and the support frame with the base plate thereon.
  • the invention is a clad plate comprising a base plate 11 having a plurality of adjacent lines of continuous bead welding 12 deposited thereon.
  • the bead welding 12 is deposited in a wave-like fashion to form, for example, a sinusoidal pattern as shown in FIG. 1, or a herringbone pattern as shown in FIG. 2.
  • the bead welding can be deposited to form a cladding comprising a single layer, or a cladding comprising multiple layers as shown in FIGS. 3 and 4. When deposited in multiple layers, the bead welding can be deposited directly over the underlying layer (FIG.
  • This wave pattern of the clad layer substantially improves wear resistance of the clad plate and reduces the problem of channel wear brought about by exposure to highly abrasive environments because the abrasive materials cannot be carried continuously within the interstices between the bead welding lines as the abrasive materials flow across the clad plate.
  • the clad plate shows greatest wear resistance when used in a manner such that the abrasive materials being handled by the clad plate move across the cladding perpendicular to the direction of bead line deposition.
  • a base plate 11 preferably comprising a low carbon mild steel, is placed upon a fixed support frame 14 over which the welding heads 16 of a carriage welding machine 17 are suspended.
  • a welding machine suitable for use in making the clad plate of the present invention is supplied by Weldtech International (Edgewood, Kentucky).
  • the size of the base plate 11 is preferably 8 feet x 20 feet and has a thickness of at least 3/16-inch.
  • a base plate having any thickness less than 3/16 inch runs a risk of being perforated during the arc welding procedure.
  • the welding machine 17 preferably has at least 4 welding heads 16 fed by wire spools 15 through wire feeders 18.
  • the welding wire 19 used is preferably 1/8 inch diameter and preferably includes a flux material therein to assist in deposition and bonding of the welding wire 19 to the base plate 11. Thus, no welding gas is required.
  • a suitable welding wire is supplied by Tricon Metals & Services, Inc. (Birmingham, Alabama) under the name "Tricon Super-C". As the wire 19 is fed through the welding tips 21, it comes in contact with the base plate 11 and is fused thereto via arc welding.
  • the welding machine 17 is movable in a longitudinal direction above the support frame 14 and the welding heads 16 are movable in a transverse direction relative to the support frame 14. Oscillation of the welding heads 16 is induced by a laterally oscillating plate 22 to which the welding heads 16 are mounted.
  • the oscillating plate 22 is driven by a chain 23 attached thereto around movable sprockets 24, one of which is driven by a motor 26 controlled by an encoder (not shown) to regulate the amplitude of the oscillations.
  • the rate of feed of the wire 19 through the welding heads 16, the rate of travel of the welding machine 17 along the support frame 14, and the oscillation of the welding heads 16 are all controlled by a central processing unit.
  • An exhaust system (not shown) is preferably mounted above the welding heads 16 to remove smoke from the area.
  • the welding tips 21 deposit a continuous stream of bead welding in at least 4 lines onto the base plate 11.
  • the welding heads 16 oscillate and travel in a wave fashion so that the bead lines form a zigzag or sinusoidal pattern.
  • the welding heads 16 are incrementally shifted and another set of bead lines are deposited immediately adjacent the previous bead lines as the welding machine 17 returns to the opposite end of the plate 11. This process continues until the desired surface area of the base plate 11 has been covered and is repeated if a multi-layered cladding is desired.
  • the final clad layer has a herringbone or sinusoidal pattern, shown in FIGS. 1 and 2.

Abstract

La présente invention concerne une tôle revêtue pourvue d'un revêtement présentant une résistance accrue à l'usure. Cette tôle revêtue est constituée d'une tôle substrat (11) sur laquelle une pluralité de lignes adjacentes de guidonnage continu (12) ont été déposées par un soudage à l'arc. Le guidonnage est déposé à la façon de vagues de façon à former un dessin sinusoïdal ou en arrêtes de poisson. Le guidonnage peut être déposé de façon à former un revêtement comprenant une seule couche, ou un revêtement comportant de multiples couches. Le dessin en vagues de la couche de revêtement améliore sensiblement la résistance à l'usure de la tôle revêtue et réduit le problème de l'usure en canal fréquemment rencontrée en cas d'exposition à un environnement hautement abrasif. En effet, les matériaux abrasifs ne peuvent pas être emportés en continu à l'intérieur des interstices entre les lignes de guidonnage lorsque les matériaux abrasifs coulent sur toute la tôle revêtue.
