What Is Arc Welding?

Arc Welding and Types of Arc Welding are permanent metal joining process. It uses the filler metal called an electrode, the heat developed by electricity to join the two metals (or two parts). The Electrode is a long and thin cylindrical metal attached to welding holder; an arc will develop results in the permanent joining of the two metals. The whole process of welding will be work on electricity.

Types Of Arc Welding:

The types of arc welding depend upon the type of consumption of the electrode and type of welding process. The different types of arc welding are.

Consumable Electrode types of arc welding:

The electrode is the filler metal which consists of flux material to prevent the welding from contamination. The consumable electrode will be melted (or consumed or used) during this welding process to join the metals, such consumption of electrode while welding is called the consumable electrode. Types of arc welding according to the consumable electrode are as follows:

  • Shielded Metal Arc Welding
  • Metal Inert Gas Welding
  • Flux Cored Metal Arc Welding
  • Submerged Arc Welding
  • Electro Slag Arc Welding
  • Arc Stud Welding

So, these are the types of arc welding according to the consumable electrode kind.

Non-Consumable Electrode types of arc welding:

The electrodes that never melt and develop flux material over the welding are called non-consumable types of welding. In the non-consumable electrode types of welding, the electrode will be responsible for the arc development. According to the Non-consumable Electrode, the types of arc welding are as follows:

  • Tungsten Inert Gas Arc Welding
  • Plasma Arc Welding

You can read in detail about these types of arc welding in the upcoming articles, Stay Tuned.

Parts Of Arc Welding:

The parts of arc welding will be varying according to the types of arc welding so, the basic parts of arc welding are listed out below. They are

What Is Arc Welding, Types Of Arc Welding - Its Working, And Advantages

Transformer:

The Transformer is one of the main parts; it is the source of the whole welding working process. The transformer is the power developer and storage device in the arc welding process.

Electrode:

The electrode is the long and thin cylindrical filler metal that is used to join the metals by adding the molten metal between the two metals.

Electrode Holder:

The Electrode Holder is the device that acts as a mediator between transformer and electrode whereas; the electrode holder will convert the power into the arc.

Cables:

The Cables are the connecting threads of the devices to transfer the power.

Working Principle Of Arc Welding:

The working principle of arc welding is simple. The whole parts and process will be work with the help of the power (or electricity). The transformer is the power storage device that helps to supply the heat to the devices. The heat required to weld the parts will depend upon the type and thickness of the material. The amount of heat supply can be adjusted at the transformer itself. The minimum power required to weld will vary between 10 Volts to 50Volts and the maximum power will be around between 230 Volts to 430 Volts. This power input and consumption will be vary according to the types of arc welding.

The connection or series of the devices can be seen in the above diagram.

The heat is supplied to the electrode holder from the transformer whereas; the electrode is hold by the electrode holder the heat is transferred to the electrode. As soon as the electrode feed to the workpiece, the cycle will be closed (the earthing should be properly maintained to achieve the close loop) and an arc will be developed.

The arc will melt the electrode and fills the gap between the two metals to make a joint. The welding joint or metals are allowed to cool for better binding or welding.

Advantages Of Arc Welding:

The advantages of types of arc welding are as follows

  • The welding gives strong and high-strength joints to the metals.
  • It can be used to weld any type of metal.
  • The types of arc welding are easy to construct and simple to perform.
  • The high thickness metals can be weld by adjusting the heat output.

We will find more and precised advantages while reading about these types of arc welding separately.

Applications Of Arc Welding:

The applications of arc welding and types of arc welding are vast and can be observed in our daily life.

  • The types of arc welding are widely observed in welding shops because the applications of arc welding are useful for every type of metal and joining.
  • The arc welding and its types are useful in factories, and automobile workshops for joining the failure parts.
  • The different types of arc welding is used at constructions for frame and column works.
  • Due to various types of arc welding easy operation, they are used to join the castiron, steel, etc pipes even at undergrounds.

We will find more and precised applications of different types of arc welding while reading about these types of arc welding separately.

Conclusion:

The arc welding and types of arc welding are basically used to join the parts. Their application is easy but their results are high and cost-effective. The failure of welding leads to damage and loss of human lives. There are many tools and testing processes to estimate the welding quality and its failures. This type of welding is a life-risking process if we do not follow the safe practice. They can lead to vision loss and even life too. So, welding will be safe until we perform it with good practices.
