Welding
can be defined as a metal
- joining
- process
by the use of heat to cause coalescence
between two or more pieces of metal. It may be performed
with or without the use of a filler metal and with or
without the application of
pressure.
Welding
is a job skill used within many trades to manufacture,
construct, produce, fabricate and / or repair objects of
metal.
From its ancient roots until today, the art and science of
welding has served well both the artisan who mastered the
craft and the culture in which the craftsman
practiced and applied this skills. The
skill of welding is very diverse and covers a wide range of

Through
historical artifacts, the art and science of welding can be
traced back a very long way. The tools, techniques the
applications and methods have changed tremendously, however,
the purposeful function has basically remained the
same. It is
believed, by some, that welding was successfully applied by
the ancient metallurgist to first craft jewelry and
utensils. The applications was later extended to become a
major factor in the manufacture, production and repair of
tools and weapons.
Today, welding is a critical force in our

commerce. A weld
is a homogeneous
bond between two or more pieces of metal, wherein,
the
strength of the welded joint equals or exceeds the strength
of the original base metal;
this is accomplished in part by controlling the
Welding
Process Variables
and the elimination of welding
defects.
