Welcome to weldingbiz. This site is to provide
welding information for both those who wish to learn welding ,
and also welders who wish to move to another level in welding,
perhaps to advance in your career or even start a business. For
instant welding information check out the welders

What Are The types Of
Metals have different characteristics that
affect their ability to be welded or cut. The welding process
involves melting the base metal parts and adding filler metal
that has the same melting temperature and characteristics of
the parent metal.
Metals are divided into two categories, ferrous
and non ferrous. Ferrous metals contain iron such as cast iron,
mild steel, forged steel, and stainless steel., where as
aluminium is a non- ferrous metal. Each metal type requires
different welding procedures and filler metals.
These are the four major Welding Types processes that
are used both in industry and for the home hobbyist.
Gas metal Arc
Also referred to as MIG or metal inert gas
welding. The most versatile and most used of all welding
processes. Uses a continuous wire feed electrode fed through a
welding gun along with a continuos flow of shielding gas.
The advantages of a mig welder are many, the
gun is easy to manipulate and keep at a uniform distance from
the weld, continuos wire feed allows longer welds to be run,
the welds remain smooth and clean because of the shielding gas.
You can weld at very low temperatures allowing welding of 22
and 24 gauge sheet metals.
Disadvantages are outdoor welding situations
where the shielding gas can be blown away in a breeze and in
tight situations where the gun nozzle limits welding. Mig
welding is deal for welding mild steel, stainless steel and
Mig welding is one of the easier processes to
learn how to weld
Gas Tungsten Arc Welding
Also referred to as TIG or tungsten inert gas
welding Tig welding is a process that generates an arc between
a non consumable electrode and the work. The electrode and the
weld are protected by a gas shield, and a filler rod may or may
not be used.
Tig welding is similar to gas welding and
requires more skill. Used for doing fine work and where a high
standard of finish is required without the need for grinding,
such as bicycle frames and food manufacturing equipment.. As
Tig welding is a very clean process its ideal for welding
stainless steel and aluminium. For a more advanced version of
the tig welding process see precision plasma welder.
Shielded Metal Arc
Mostly referred to as stick or arc
welding. How to arc weld involves heating the base
metal to fusion by an electric arc using a welding electrode.
The covering on the electrode provides both a flux and
shielding gas for the weld.. Electrodes range in thickness from
2 mm for light work and up to 5 mm for heavy steel.
Stick welding is used for fabrication,
construction and repair work, more suited to metal thickness 4
mm and upwards. Thinner metals and aluminium are more suited to
the GMAW process. See; how to weld aluminium.
Oxyacetylene Welding or
Learning how to oxyacetylene weld is a relitavely easy
process to master and uses a gas flame to melt base metals and
fuses them together. The gas flame is created by the combustion
of oxygen and a fuel gas such as acetylene, propane, butane or
natural gas. The hottest of any gas flame is capable of melting
Gas welding today is generally restricted to
welding thin sheet metals (see also; how to spot weld) and
brazing of mild steel, and copper pipe work. , Braze welding is
used for joining dissimilar metals and metals of different
thickness and often used to repair cracked or broken cast
Other welding topics covered on this site
include Plastic welding . We also have resources
for welding equipment and supplies including welders and
auto darkening Welding helmets.
With the relative scarcity of trained
welders in many regions of the country welding can be a
rewarding and exciting career. Personnel are sought after
in felids in civil construction, machinery, ship building,
agriculture, food processing, automotive,
furniture, technology and many more, so get
out there and learn how to weld.
