With this paper, I will illustrate the advantages plasma-arc welding has over hand or furnace brazing, especially with pearl enhancers, bangle bracelets and tennis bracelets. (Fig. 1) I first discovered plasma arc technology at the 1987 Santa Fe Symposium while discussing the use of MIG or TIG welders for filling pits in castings. Upon further research, I applied plasma-arc technology to the hinge assembly on jewelry product producing fine quality in the weldment area (i.e. no pits or circles at rivet pin weld).
