What Is Welding

By heating two or more surfaces to a melting point, welding joins two or more pieces of metal or thermoplastic. Typically, this process involves applying heat and pressure to the surfaces being joined, causing the materials to melt and fuse.

History of the Welding

History of Welding Method/Process

·         Earliest stage of welding is known as forge welding

·         16th century - Soldering process used for brazing silver and copper

·         18th century - Gas welding and Arc welding

·         19th century - Fusion welding, Metal electrode welding and Carbon arc welding.

·         20th century - Electric arc welding

Several new welding technologies and techniques have emerged, such as laser welding, electron beam welding, and friction welding. As a result of these techniques, welding was more precise and controlled

Types of Welding

·         Arc welding

·         Gas welding

·         Resistance welding

·         TIG welding

·         MIG welding

·         Laser welding

·         Plasma welding

Types of Welding

Arc Welding

Electric arcs melt metal and create bonds between pieces when they are used to weld. It can be done with stick electrodes, MIG wire, or TIG rods (tungsten inert gas).

Gas Welding

In gas welding, acetylene and oxygen are burned to create a flame that heats the metal and bonds it. It is often used to repair thin materials or to weld thin materials together.

Resistance Welding

Heat is generated by electrical resistance during resistance welding, which creates a bond between two pieces. Sheet metal and dissimilar metals are often welded using this process

TIG Welding

TIG welding, tungsten electrodes and shielding gases are used to create a precise, high-quality weld. Welds created using this process are often thin or aesthetically pleasing.

MIG Welding

To create a strong, high-speed weld, MIG welding uses a consumable wire electrode and shielding gas. Welding thicker materials or welding in a production setting often requires this process.

Laser Welding

During laser welding, metal is melted and bonded between two pieces with the help of a high-power laser beam. Precision welding or difficult-to-weld materials are often welded using this method.

Plasma Welding

Plasma welding creates a bond between two pieces using a focused plasma arc. The welding of thin and highly conductive materials is often performed with this process.

Advantage of Welding

·         Strong and Durable

·         Versatility

·         Cost-effective

·         Increased productivity

·         Improved aesthetics

·         Reduced weight
