What is welding? Welding is a process that joins metal parts together by using heat. A welding machine creates an electric arc between two pieces of metal, melting them together. Welders use different rods and tips to create the weld, which can be very strong. 

There are many types of welding, each with its own strengths and weaknesses. In this blog post, we’ll take a look at the different types of welding and what makes them unique. We’ll also provide a guide on how to get started in the welding industry. So whether you’re looking for a new hobby or thinking about starting a career in welding, read on!

Welding may seem like a simple process, but it is actually a very intricate and difficult art. Welders must have extensive knowledge of metalworking, as well as strong problem-solving skills. They must also be able to work accurately and efficiently under pressure. 

Welders are in high demand in the manufacturing industry, where their skills are essential for creating everything from cars to skyscrapers.

What Is Welding?

Welding is a process where two or more pieces of metal are welded together by means that include heat, pressure, and/or both. This forming can be used on any type of material including steel alloys like AISI 304 which makes up most semi-underground pipes in airports worldwide.

The parts that are joined to each other can have a variety of uses, depending on the material they’re made from. Some materials require special processes and techniques for joining them; these types of joins are called ‘welds.’ A useful term not usually found in dictionaries but descriptive nonetheless- welding refers specifically as bonding together two pieces without melting any part into it.

In many cases, consumables are chosen to be similar in composition with the parent material. When this is not possible due to their brittle or sensitive nature however it becomes necessary for welders working on these types of objects to use different fillers that have much stronger properties than what they would need if creating a homogenous joint– these types being heterogeneous (or mixed). 

The completed piece can then become known as either: 

A). A “weldment” when containing both solid and fluid components; 

B )just ‘a’ fusion between two elements

How Does Welding Work?

For Metals 

Welding is one of the most popular methods for joining metals together. The process starts by heating both pieces up until they’re molten, which allows their molecules to bond easier through chemical reactions. 

Then you cool them down fast enough so that this bonding doesn’t occur in your workplace environment. 

The result is an integral part made from steel or another more reactive material paired perfectly with its significant counterpart without any contaminants getting mixed into either weldment (piece).

For Plastic 

Plastics welding is a process that melts and fuses two or more plastics together using heat, pressure, and sometimes chemicals. There are three stages in this joining method – -preparation of the surface for external/internal heating methods depending on which type you use 

-application with flame (external)  

-submerged arc technique( Internal ) to merge them at their molecules level so they become one strong durable material again

Types of Welding 


An arc is a small but powerful flame that weaves its way through any material, heating it up and making everything else melt away. 

There are many types of welders out there: MIG (Metal Inert Gas), TIG (Tungsten inert gas) GTAW/GMAW – these terms refer to different techniques in which metal or certain other substances may be melted by electricity produced during the welding process while keeping separation between them at bay with shielding gases such as argon stellar nitrous oxide, etc). 

The filler metal is a necessary evil in the process of welding. It ensures that there are no gaps or cracks between two pieces being joined together, but it also takes up space and can be difficult to work with depending on what type you use for your project’s needs – which means this task may not always end up looking so pretty.


How does heat affect the way we bond? 

The answer lies in a process called fusion, which combines two or more materials together by using mechanical friction. 

The common types of welding processes that can create this bonding effect are; 

  • Friction Stir Welding (FSW),
  • Friction stir spot Welder( FSSW)

Friction welding is one of the most common methods for joining together various materials, such as steel or aluminum. It can be used on wood too.


Laser beam welding is a fast and efficient way to join thermoplastics or metal pieces together. 

The process uses lasers that provide intense heat, making it ideal for joining at high speeds in the automotive industry where quality must be maintained throughout production lines. 


The two most common types of welding in the automotive industry are resistance spots and seam. 

Resistance spots use heat delivered between two electrodes to melt metal on small areas, while seams have rotating wheels that create an edge when heated up so they can be clamped together easily by hand or machines without any need for heavy machinery. 


Welding is a process that has been used for centuries to create objects from smaller items to bigger crafts. The most common types of welding are plastic, wood, and metal. While welding requires intense expertise, it can be an extremely rewarding process when done correctly. 

The process is done with specialized tools and equipment, which can create strong welds on any type of surface – even those that are hard to reach.

Welders must work quickly though because they need enough heat (which comes from the electricity) in order to make sure everything sticks properly before it cools off too much.
