The Welding and Brazing of the Refractory Metals Niobium, Tantalum, Molybdenum and Tungsten - a Review*

This review covers the present and future problems in the development and welding of niobium, tantalum, molybdenum and tungsten and their alloys. Their metallurgical characteristics are discussed together with the influence of impurities and alloying elements on mechanical properties, alloy development and weldability. Other factors briefly discussed are availability, high temperature strength,...

Developing and Easing the Brazing Method

Brazing generally require cumbersome apparatus be it induction, vacuum or torch brazing. In torch brazing, metals are joined by using the oxyacetylene cylinder. It thus becomes difficult to carry out brazing at the places where it is not possible to take heavy gas cylinders and brazing apparatuses. So it is tried to figure out the method to carry out brazing at places where conventional brazing...

Wettability of Brazing Filler Metals on Copper and Copper Alloys

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...

Brazing & Soldering Today

Brazed components play an essential role in consistent joining techniques. The brazing process is characterized by low process temperatures and fast processing times, compared to welding techniques. Beside the resulting low manufacturing costs, brazing can join dissimilar materials, e.g. metals and ceramics. Consequently, brazing provides potential for many industrial applications like the prod...
