Abstract

Jewelry neck chain is joined by age-old techniques, the most popular being the rather involved solder powder method. The solder core method of chain manufacture is a simpler process and offers the possibility of higher productivity. Neat narrow joints are formed, and a color match between the solder and parent alloy may be approached. This is particularly important in the case of platinum alloys that have a high melting point, necessitating the use of solders with compositions substantially different from those of the parent alloy. The solder core method also lends itself to the possibility of higher levels of automation.
