Abstract
The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line of localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.

A method of producing a composite rod from a braze material and a sheet of material comprising cermet, the method comprising:
- scoring a surface of the sheet with a laser to produce a thermal stress and at least one line of localized stress;
- causing the sheet to break along the line of localized stress, thereby to produce a plurality of cermet chunks;
- and
- combining the cermet chunks with the braze material to produce the composite rod.
A method of hardfacing a surface to be hardfaced using a sheet of material comprising cermet, the method comprising:
- scoring a surface of the sheet with a laser to produce a thermal stress and at least one line of localized stress;
- causing the sheet to break along the line of localized stress, thereby to produce a plurality of cermet chunks;
- and
- brazing the cermet chunks to the surface to be hardfaced.
