Welding has various processes for fusing metals

Welding is a technique by which welder connect different materials and fuse them. They can be any metals like aluminum, stainless steel, magnesium, cast iron, steel, brass and plastic or polymer such as synthetic and natural materials.
The technique can be unsafe, if welders carry out the work practice without appropriate safety measures.

There are various types of power sources can be utilized for this process such as laser, gas flame, electron beam, ultra sound, electric arc and friction. Thanks to highly developed technology to provide appropriate welding machine and proper protection as the threat of injury and death related to process can be reduced to a great extent. An appropriate machine has to be utilized to weld different kinds of materials jointly, so that the outcome will be up to the expectation.

A welder should know the use of the machine and the purpose it is going to be employed. Then only he can select the proper type of welding machine that is required. He also can choose other equipments and tools that can be needed along with machine. Some of the tools that might be required are: welding helmet, curtain, torch, gauntlet and goggles. However, with the proper machines, welders usually need to have excellent skill and concentration. They also have sufficient technical knowledge on various materials and great practice in the entire process.

Welding is divided into three different processes such as shield metal arc, tungsten inert gas and metal inert gas.

Shield metal arc welding:
This arc fusing is also called as stick welding or Manual Metal Arc. Normally it is utilized for blending cast iron and steel metals or stainless steel. The various tools required for this form of bonding are: constant supply of power, an electrode, a work clamp and an electrode container.

Tungsten inert gas welding:
In this type of fusing, those metals that react quickly such as aluminum and magnesium can be bonded together. In this TIG technique, various types of joints, whether it is t-joint, butt joint, corner joint or lap joint can be fused and completed manually. The process is utilized for fixing brass, magnesium alloys, stainless steel, and titanium, aluminum, copper and steel. The different equipments needed for this are: non fragile tungsten electrode, inert gas and individual filler stuff.

Metal inert gas welding:
This process is also known as GMAW (Gas Metal Arc Welding), in which aluminum can be fused with other non-ferrous metals and it is also used to connect various kinds of alloys as well as metals. It is very quick method compare to other processes and it uses only little splash in the entire process. The different tools needed are: an electrode wire, wire supply unit, a welding gun and defending gas supply. This technique is mostly utilized in sheet metal manufacturing units; therefore it is greatly used in automobile business.
