Claim Text:
1. Method to produce a bead for use with a sawing cord comprising the steps of: holding a metal tube on at least one of its ends; starting to clad said tube by a laser cladding system whereby a supply of metal matrix material is melted by a laser beam on said tube thereby forming a pool of molten metal matrix material and; forming a track on said tube by moving said laser cladding system relative to said tube in a rotational movement, said track building an abrasive layer on said tube; stopping the cladding of said tube; allowing the thus formed bead to cool down; wherein said abrasive layer has a mass that is larger than the mass of a portion of said tube radially under and covered by said abrasive layer, and said relative rotational movement results in a circumferential tube speed of at least 5 mm per second.
