Introduction
When designing and making a brazed joint, quite apart from the physical properties of the brazing
alloy and the mechanical properties which can be expected from the joint, it is important to know
the brazeability as a function of the operating conditions adopted. The determination of wettability
has already been the subject of numerous investigations and proposals regarding testing methods. In
carrying out these investigations, the most frequently used methods are based on the spreading of a
drop, or on the measurement of surface tension, but they in fact only take one element of the problem
into account. It is important to know not only the way in which the liquid filler metal wets the surface of
the parent material but also how this same liquid filler metal behaves in a given gap between the joint
components when diffusion takes place.
In this document, brazeability is defined as a total degree of joinability. The joinability consists of both
wettability and fluidity to permit distribution into a joint, i.e. ability to fill a joint gap, although total
brazeability includes performance of the physical, and mechanical properties in services.
As the tests to be designated for brazeability, three methods are introduced in this document. The
traditional varying gap test is described for the most real ability to fill the gap, but it requires a private
sample preparation and special evaluation technique with X-ray device. The T-joint test is newly
developed to investigate ability to fill the gap in an easier manner. It can be easily operated at industrial
laboratories. Moreover, a simple spreading test is designated for practical convenience.
