The high power test model of biperiodic L-support diskand-washer was fabricated. Among some trouble in the fabrication, the main one was a vacuum leak in a brazing process. The repair test of the leak showed a good result; four units were recovered out of five leak units (recover rate 80%). While an accelerating mode frequency was tuned at an operating frequency of 2857 MHz by squeezing method,...

Abstract To increase productivity when joining galvanised sheet metal, metal inert gas (MIG) and tungsten (TIG) arc brazing are combined in a hybrid process. This coupling of two processes increases speed reduces weld reinforcement the tendency to spatter. Because arcs 6 mm apart, they influence each other. Therefore, blowing action is major challenge brazing. A current modulation optimal relat...

Ag is used as a useful alloying element in brazing filler metals. It clear that the addition of has positive effect on melting temperature, wettability, conductivity and mechanical property For this reason, although very expensive, it still widely many research production. In study, was focused obtaining both high strength cost-effective joints by using metals containing different levels Ag. Me...
