Involved
in
Hardfacing -
1. Determine the exact composition of the base metal because it influences the success and quality of the surfacing method.
2. Determine the type and degree of wear on the base metal.
3. Determine the welding position of the job.
4. Estimate the area that needs to be hardfaced.
5. Select an appropriate hardfacing alloy.
6. Select an appropriate hardfacing method.
7. Prepare the surface to be hardfaced.
8. Apply the hardfacing alloy on the base metal.
9. Impart proper surface finish to the hardfaced base metal component.
