Information Technical
Service While
the majority of joining and rebuilding problems can be solved with a selection
of ten to fifteen All-State
alloys, there are two ways in which All-State can help you with the unusual or
difficult-to-solve problem: first,
by offering you a wide variety of versatile, multi-use alloys in electrode, wire,
rod, powder, and paste form with matching
fluxes. Second, by offering you the technical service or assistance of our experienced
personnel. Business
Principle Providing
the right combination of products and technical service to produce superior results
is the principle to which
All-State has always adhered in serving the maintenance and repair welder. The
effect of this principle is evident
in the world-wide acceptance and popularity of All-State products and their ability
to solve metal joining problems
at a lower cost, or in less time, or both. Important
Notes on the usage of terms in this book Temperatures
Service or
working temperature signifies
the maximum recommended temperature the alloy must withstand after
application to the workpiece and when
the workpiece is in service. This temperature is the maximum beyond
which the alloy begins to lose significantly
its strength, toughness, and/or wear resisting characteristics.
Liquidus (fusing temperature)
signifies the temperature at which the alloy will melt
if a complete transformation from
solid to liquid takes place. Solidus
(melting point) signifies the temperature
above which the alloy becomes slightly viscous to freely liquid.
The range between solidus and liquidus
indicates whether a thick fillet-type deposit or a thin overlay-type deposit
will result. Thin flowing, highly liquid
alloys have a narrow range. Conversely, bead forming alloys used for build-up
are thick, viscous
materials with a wider range.
