Welding is a simple
process of joining more than one material by applying different types of
friction and external heat. It is widely used in manufacturing and construction
industries.
There is a popular
misconception that welding electrodes are used only for
dealing with metals. This is not true. Welding can also be done for plastic
materials. In this blog, we will discuss in details about the most popular
welding techniques which are applied in various fields.
Let’s get started:
- Arc Welding – This welding technique involves
melting materials before joining them. An electric arc is used. This
electric arc is brought between the subjected materials by using
preferably a non-consuming electrode. This technique is very effective and
can easily work on even the highest strength metals such as carbon steel.
This is because the electric arc can create high temperatures which can
even go up to a staggering 3,500°C. This type of welding is mostly used in
the manufacturing sector and the automobile sector. There are different
types of Welding Arcs available in the market such as Submerged Arc
Welding (SAW), Plasma Arc Welding (PAW), Shielded Metal Arc Welding
(SMAW), and more.
- Oxyacetylene Welding – Commonly known as Gas Welding,
this welding technique involves melting the materials concerned by using
heat from a concentrated flame. The metals are joined after getting melted
first. This technique revolves around the technique of concentrated flame.
Here, the flame is controlled by using a welding torch. The welding torch
is controlled by the welder which checks the flow of the concentrated
flame used for melting the metals. The combination of oxygen and acetylene
can work on strong metals as it is capable of producing heat around
3200°C. Gases such as hydrogen and propane are also used as other fuel
gases in this welding process. The oxyacetylene welding process is very
popular because it has numerous advantages. It is low cost and maintenance
can be easily transported, and easy to handle. It is mainly used for
fabrication of sheet metal and joining thin metals. All these make it
incredibly handy in aircraft and shipbuilding industries which involve
working with heavy and strong metals.
- Tungsten Inert Gas Welding
– This
welding process mainly uses an electrode made of tungsten to create an arc
between the materials. Tungsten electrode is non-consumable and so it is
not consumed in the welding process. One of the biggest benefits of using
this welding process is the fact that it works incredibly well in welding
non-ferrous metals such as copper, aluminium, magnesium, nickel, and more.
It is mostly used in the automobile industry.
- Flux Cored Arc Welding – It can be subdivided into 2
parts – self-shielded flux core welding and gas shielded flux core
welding. In the self-shielded flux core welding, the flux inside the
electrode produces slag and gas when heated. They do not require any
external agents for the heating process. In the gas shielded flux cored
welding technique; an external gas is used to produce the slag. The
shielding gas can be controlled. This is why it is so popular among
welders.
Finding top-quality welding electrodes is not a big task anymore. You
can find this type of tools at different online e-commerce stores. The popular
e-commerce stores are bombarded with world-class welding electrodes
manufactured by some of the most renowned brands such as Tata Agrico.
Quality is the most
important parameter when you are investing in a welding electrode. So, it is of
utmost importance to choose products manufactured by top brands. It promises
durability and good performance on a consistent basis.
