How to Tig Weld?
Gas tungsten arc welding (GTAW)
also known as tungsten inert gas(TIG)
welding, is an arc welding process that
uses a non consumable tungsten
electrode to produce the weld. The
welded area is protected from getting
contaminated with the help of shielding
gas and a filler metal such as aluminum
or stainless steel. Gas tungsten arc
welding can weld stainless steel and
light nonferrous materials like
aluminum and magnesium. Tungsten
inert gas does stronger and higher
quality welds when compared to its
competing procedures like shielded metal arc and gas metal arc welding. Tig
welding is complicated, difficult and much slower than other welding
procedures like mig or arc welding.
Manual tig welding is considered
most difficult among all the welding
procedures in the industry. Because
welding operator has to maintain a
short arc length, make sure that
great care and skill are required to
prevent contact between the
electrode and the work piece. TIG
Welding generally requires two
hands because the welder manually
feeds a filler metal into the weld
area with one hand while
manipulating the welding torch in
the other.
In the beginning, tig welding may
be considered complex and difficult task but through regular practice and
tuition it becomes easy for the welding operator to perform the task. In tig
welding, very less cleaning is required, the finished weld is neat & tidy
allowing an artistic feel to the work. Major examples of quality tig welds are
bicycle frames, marine fittings, interior kitchen fittings and steel artwork.
