What Is Welding?

Welding is one of the most essential and widely used industrial processes in the world. Over the years, it has revolutionized the construction of structures, machines and components, transforming them into durable and reliable end products.

According to the U. S Bureau of Labor Statistics, the global welding industry is estimated to be worth over $20 billion. An estimated 7 million welders are employed across the world in various industries, from aerospace and automotive to shipbuilding and petrochemical.

Welding plays a crucial role in maintaining the structural integrity of these products, ensuring their safe, secure and sustainable use. But what is welding exactly?

Let’s dive into the details.

What is Welding?

Welding is a fabrication process that involves using heat or pressure to unite materials, most commonly metals or thermoplastics. The process can be used to join materials together permanently or it can be used to cut materials apart.

It can be used in a wide range of applications, from automotive repair to manufacturing.

Types of Welding

There are many different types of welding processes.

The most common types include;

Arc Welding

Arc welding uses an electrical current to heat and melt metals in order to bond them together. It is a very popular and versatile type of welding, as it is relatively fast, economical and easy to learn.

Gas Welding

Gas welding, also known as oxy-acetylene welding, creates a heat betweeb a gas flame and the metals being welded. It is mainly used for joining thin pieces of metal together and for cutting.

TIG Welding

TIG welding, also known as gas tungsten arc welding (GTAW), is a versatile welding technique that can be used on a variety of materials.

It uses a non-consumable tungsten electrode to create the arc and pass the current to the material.

MIG Welding

MIG welding, also known as gas metal arc welding (GMAW), is a form of arc welding that uses a consumable wire electrode to create an arc and pass the current to the material.

It is often used for welding aluminium and other light alloys, as well as steel.

Benefits of Welding

Welding has a wide range of benefits, including:
  • Welding is strong and reliable
  • It creates permanent joints between metals
  • It is relatively fast to do
  • It can be used on a variety of materials
  • It is economical and cost-effective


Welding is a fabrication process that is used to join or cut materials together. There are many different types of welding which make it a very versatile process, and it has a wide range of benefits, such as being strong and economical.
