Welding
is the process of heating two pieces of metal so that they join and form a firm
joint. To do this, one needs a high degree of ability and technology. There are
different ways of welding; some need machinery and advanced technology,
including lasers, beams, etc. Welders work with metals, alloys and materials.
Oxy-Acetylene
Welding is a welding process which requires the use of a special welding torch
to combine oxygen and acetylene gases and produce a fire of up to 6,300
degrees. This process is widely used to manufacture wrought iron gates and
fences. This type of binding is normally used in industries that work with
copper pipes, including brass wear plates and brass sticks.
Gas
Cutting Using Oxy-Acetylene
The
majority of the gas torches have a lever style valve that facilitates an extra
burst of oxygen through the cutting torch to the job which has been heated to
melting point. This shot of oxygen burns away the parent alloy with high force
and rate, thus producing a narrow cut in the metal. In this way, welders can
cut easily, either manually or by machines. Manual gas cutting can cut metals
of 1/16 of an inch and up to two inches, whilst profile cutting can cut steel
up to a thickness of four inches.
TIG
welding
Tungsen
welding or TIG welding uses a non-consumable tungsten electrode to create the
weld. The weld area is protected by an inert shielding gas and a filler metal
is used. This type of welding is used to thin sections of stainless steel and
metals such as aluminum, copper and magnesium.
Plasma
arc welding
In
plasma arc welding, the electric arc is formed between an electrode and the
work piece. The process is similar to TIG welding.
Laser
Beam welding
Laser
Beam welding is a meld technique where multiple pieces of metal are joined via
the use of a laser. This type of welding is used in high volume applications,
such as in the automotive industry.
Welding
sticks of good quality should be obtained, so that the welding result is
significantly better. Welding Rod is used to place
additional metal to the weld. Hence, it needs to suit the metal. Welding wire
and oxy-acetylene sticks are made of Norway steel. Choosing the right welding
rod is essential as it will help to determine the success of a weld and the
strength of a joint. If you choose the wrong pole, it can produce a meld that's
either too hard or brittle.
