Metal welding is the process of joining two pieces of metal by using heat to melt and fuse them together, sometimes with the addition of a filler metal. It creates a strong, continuous bond and is widely used in construction, manufacturing, and repair work.

Common Types of Metal Welding

Gas Welding

Uses a combination of acetylene and oxygen gases to produce high heat that melts the metal for welding.

Arc Welding

Utilizes an electric arc between the electrode and the workpiece to generate the heat needed to melt the filler rod and base metal.

TIG Welding (Tungsten Inert Gas Welding)

Uses a tungsten electrode and an inert shielding gas (like argon) to protect the weld area from atmospheric contamination.

MIG Welding (Metal Inert Gas Welding)

Involves continuous feeding of a bare wire electrode, with an inert gas shielding the weld to prevent oxidation.

Resistance Welding (Pressure Welding)

Joins metals by applying heat generated from electrical resistance and pressure, commonly used for spot welding.

Submerged Arc Welding (SAW)

Uses a bare wire electrode under a layer of granular flux to protect the weld zone from air contamination during the process.

Summary
Welding is a versatile technique with several methods suitable for different materials and applications. Understanding the types of welding helps you choose the most efficient and safe technique for your project.
