## Commonly used What types of welding methods are there?

Welding is a process that permanently joins two or more metal parts and is widely used in manufacturing, construction and repair. The different types of welding methods are listed below:

1. Arc welding

##Metal Inert Gas Arc Welding (MIG)
• : Use continuous wire as filler metal and proceed under inert gas protection.
Gas Metal Arc Welding (GMAW)
• : Similar to MIG welding, but uses carbon dioxide or a gas mixture as the shielding gas.
Tungsten Inert Gas Arc Welding (TIG)
• : Uses a tungsten electrode for the arc and a separate filler metal strip.
Plasma Arc Welding (PAW)
• : Uses a plasma arc to melt metal, providing high welding speed and accuracy.

2. Resistance welding

#Spot welding
• : Local heating of specific areas on stacked metal plates And pressurized to form a nugget.
Seam Welding
• : Similar to spot welding, but uses a continuous wheel to create a longer weld.
Projection welding
• : A raised projection is formed on the corresponding areas of the two metal plates, and then pressure and electricity are applied for welding.

3. Friction welding

Rotating friction welding
• : By rotating one workpiece into contact with another fixed workpiece, Frictional heat is generated and a weld is formed.
Obvious Friction Welding
• : Similar to rotary friction welding, but uses an oscillating motion to create friction.
Linear Friction Welding
• : Moving one workpiece linearly onto another while applying pressure and friction.

4. Laser welding

Fiber laser welding
• : Use fiber laser to melt metal, providing extremely high precision and weld quality.
Carbon dioxide laser welding
• : Uses a carbon dioxide laser to melt metal and is suitable for high-power welding applications.

5. Ultrasonic welding

Ultrasonic metal welding
• : Use high-frequency ultrasonic vibration to generate friction heat and form welds seams, suitable for thin metal and precision parts.
Ultrasonic plastic welding
• : Similar to ultrasonic metal welding, but used to weld plastic materials.
In addition, there are other types of welding methods, such as electron beam welding, diffusion welding and brazing, which are suitable for specific applications.
