## What is Welding Machines?

![Welding Machines Feature](https://www.shivshaktimetal.com/wp-content/uploads/2025/11/Welding-Machines-Feature.webp)

To understand **what is welding machines**, think of them as power sources that generate controlled heat to join metals together.

In simple terms:

A welding machine is equipment that supplies electrical energy to create an arc or heat source used to melt and fuse metal components.

Different welding machines use different technologies such as electric arc, laser beam, or plasma arc to produce the required heat.

## How Welding Machines Work

Most welding machines operate using this basic principle:

1. The machine converts input power into controlled welding current.
2. The current creates an electric arc between electrode/wire and base metal.
3. The arc generates intense heat (above 3,000°C).
4. The base metal melts.
5. Filler material (if used) forms a strong joint after solidification.

Some advanced machines like laser or plasma use focused energy beams instead of traditional arc.

## Types of Welding Machines

Understanding the types helps clarify **what is welding machines** in practical industrial use.
