Zusammenfassung:	Une poudre d'alliage recouverte de brasure est collée sur un noyau sphérique puis transformée en une couche d'alliage continue par brasage. The invention relates to a method of producing and joining superalloy balls by means of brazing and to objects produced with such joints. According to one aspect of the invention, an alloy powder covered with a brazing solder is bonded to a spherical core and subsequently transformed into a continuous alloy layer by means of brazing.
