Types of Welding

 Arc Welding:

 Arc Welding

This category includes variety of common manual, semi-automatic and automatic processes. These include metal inert gas (MIG) welding, stick welding, tungsten inert gas (TIG) welding, gas welding, metal active gas (MAG) welding, flux cored arc welding (FCAW), gas metal arc welding (GMAW), submerged arc welding (SAW), shielded metal arc welding (SMAW) and plasma arc welding.

Uses:

These techniques usually use a filler material and are primarily used for joining metals including stainless steel, aluminium, nickel and copper alloys, cobalt and titanium. Arc welding processes are widely used across industries like oil and gas, power, aerospace, automotive, and more.


Friction Welding:

 Friction Welding

Friction welding techniques join materials using mechanical friction. This can be performed during a sort of ways on different welding materials including steel, aluminium or maybe wood.
The mechanical friction generates heat which softens the materials which mix to create a bond as they cool. The manner in which the joining occurs is dependent on the exact process used, for example, friction stir welding (FSW), friction stir spot welding (FSSW), linear friction welding (LFW) and rotary friction welding (RFW).
Friction welding doesn't require the use of filler metals, flux or shielding gas.

Uses:

Friction is usually utilized in aerospace applications because it is right for joining otherwise 'non-weldable' light-weight aluminium alloys.
Friction processes are used across industry and also are being explored as a way to bond wood without the utilization of adhesives or nails.


Electron Beam Welding:

 Electron Beam Welding

This fusion joining process uses a beam of high velocity electrons to join materials. The kinetic energy of the electrons transforms into heat upon impact with the workpieces causing the materials to melt together.
Electron beam welding (EBW) is performed in a vacuum (with the use of a vacuum chamber) to prevent the beam from dissipating.

Uses:

There are many common applications for EBW, as are often wont to join thick sections. This means it can be applied across a number of industries from aerospace to nuclear power and automotive to rail.


Laser Beam Welding:

 Laser Beam Welding

Used to join thermoplastics or pieces of metal, this process uses a laser to provide a concentrated heat ideal for barrow, deep welds and high joining rates. Being easily automated, the high welding speed at which this process can be performed makes it perfect for high volume applications, such as within the automotive industry.

Uses:

Laser beam welding are often performed during a ir instead of in a vacuum like with beam joining.


Resistance Welding:

 Resistance Welding

This is a fast process which is commonly used in the automotive industry. These processes are often split into two types, resistance spot welding and resistance seam welding.

Uses:

Spot welding uses heat delivered between two electrodes which is applied to alittle area because the workpieces are clamped together.
Seam welding is analogous to identify welding except it replaces the electrodes with rotating wheels to deliver endless leak-free weld.
