filler metal suggestions “match” the base metal properties; that is, the yield and tensile strength are expected to meet or exceed the minimum specified properties of the steel.

Matching filler metal is typically required for complete joint penetration groove welds in tension. However, fillet welds loaded in shear seldom require. There are many different Specification for brazing filler metal book filler metal (BFM) families, and so, for easier identification, an orderly arrangement, such as that shown in the American Welding Society’s A Specification for BFMs in Fig.

The document specifies requirements for brazing of the test piece, testing of the test specimen, essential variables and their range of qualification, acceptance criteria, brazing procedure qualification record (BPQR) and brazing procedure specification (BPS).

Many of these alloys are also available in a Tri-metal form. These Trimet® alloys consist of two layers of brazing filler metal clad onto a core of copper.

This eases the stresses that arise due to the differences in thermal expansion between the carbide and base metal and is particularly important when joining carbides larger than one half inch.

This means that elements with high vapor pressures-such as zinc, cadmium and lead-are limited to very low percentages (% - % maximum allowable percentages).

and filler-metal type, heat source, and application method. razing joins similar and dis- similar materials by heating them in the presence of filler metal having a liquidus above F and below the solidus of the base material. During brazing, filler metal flows between fitted sur- faces of the joint by capillary ac.

Brazing filler metals of the first type were compositions consisting of 40% filler metal (Ni–9Co–14Cr–Al–B) and 60% filling agent (Rene alloy powder).

Filler metals of the second type additionally comprised 15–25% of a silicon-containing eutectic-composition filler metal (Ni–12Si), due to the decreased content of boron. In addition to the metals being joined, brazing has two important requirements -- a filler metal and a source of heat to melt the filler.

We're going to look at each of these in greater detail, starting with the filler metal. A brazing filler begins with one of several common primary metals: silver, aluminum, gold, copper, cobalt or nickel. Silver Braze 63 is a low temperature brazing filler metal developed for use on serious stainless steels for maximum resistance to interface corrosion.

It can be used onand serious stainless steels and other alloys for combined brazing/heat treatment with flux, or in protective atmosphere (including vacuum) furnaces.

Brazing is a process of joining metals in which, after heating to a suitable temperature, molten filler metal is drawn by capillary attraction into the space between closely adjacent surfaces of the parts to be joined. In general, the melting point of the filler metal is above °C but is always below that of the parent metals.AWS A - Standard Symbols for Welding, Brazing, and Nondestructive Examination - $ Product Code: ISBN: Binding: Paperback.
