Welding, basically, is the process of joining metals. While welding has been in existence for many years, these days welders, or welding machines, make it possible to produce extremely strong joins between metal objects.
Welding, in some capacity, has been around for centuries, but it wasn't really until the 19th century that the technology really began to take off. With the arrival of the 20th century, and especially World War I, welding and welders entered a new age.
Arc welding, which is still popular these days, was used during that era to build boats, bridges, aircraft, trucks and just about anything else that was made of metal. Since then, a whole range of welders and welding technologies have been developed. Here is an overview of

It forms sufficient temperatures to melt the metals and create a durable join. There are a number of different types of arc welding, these include shielded metal arc welding (SMAW), gas metal arc welding, metal inert gas (MIG) welding and tungsten inert gas (TIG) welding, to name just a few examples. All in all, arc welding remains by far the most common form of welding that is used.
Gas welding - Gas welding processes such as oxyfuel welding, also known as oxyacetylene welding, have become somewhat dated in recent years but remain among the most versatile types of welding. Not only can they be utilized to join metals, the equipment is also ideal for cutting metals, brazing and melting. The gas welding flame, a mixture of acetylene and oxygen, can attain temperatures as high as 3,100 degrees celsius.
Resistance welding - While not as popular as arc or gas welding processes, resistance welding can be ideal in certain situations, though it can be costly. Heat is made by passing a strong current through two pieces of metal. The resistance caused by the contact of the two pieces of metal makes them melt at the weld area and makes a
