Caden edge welding process
View Patent ↗A method and apparatus for applying a wear coating to the back side of a wear part.
1. A ground engagement wear part comprising a front face and a back face opposite thereto, wherein a wear resistant coating is welded to the back face and the front face is uncoated.
2. The wear part of claim 1 where the wear resistant coating is tungsten carbide coating.
3. An engagement tool comprising a leading face and a back face, wherein only the back face is coated with a substantial thickness of wear resistant coating.
4. A method of coating a wear part with a wear resistant comprising coating only the back face of a wear part with a wear resistant coating.
5. The wear part of claim 1 wherein the wear resistant coating is confined to the bottom of the back face adjacent to the front face.
6. The wear part of claim 1 wherein the wear coating has a substantial thickness.
7. The wear part of claim 1 wherein the wear coating is applied without an annealing step.
8. The wear part of claim 1 wherein the wear coating extends the life of the front face by protecting the back face from wear.
9. The wear part of claim 1 wherein the wear coating does not interfere with the flow of material over the front face of the wear part.
10. The wear part of claim 1 wherein the application of the wear coating does not substantially change the ductility of the front face.
11. The wear part of claim 1 wherein the wear part is a ripper.
12. The wear part of claim 1 wherein the wear part is a sweep.
13. The wear part of claim 1 having an edge between the front and back faces, and said wear coating extends from the back face onto the edge.
14. A ground engagement wear part comprising a forward face and a leeward face opposite thereto, wherein a wear resistant coating is welded to the leeward face and the forward face is uncoated with wear resistant coating.
