Types of Electric Metal Arc Welding

Given Below are the types of Electric Metal Arc welding :

• Shielded Metal Arc Welding
• MIG (Metal Inert Gas) Welding
• TIG Welding (Tungsten Inert Gas)
• Carbon Arc Welding
• Plasma Arc Welding
• Submerged Arc Welding
• AC Arc Welding
• DC Metallic Arc Welding
• Hydrogen Arc Welding

Shielded Metal Arc Welding

In this arc welding, when the gap between electrode and metal is smaller it generates electric arc of high intensity which is used to weld(join) metals.

The metal electrode used in welding process can be either consumable or non consumable. We can use both based on the requirement.

Electrode should not be aligned perpendicular to workpiece, It should be at some angle.

MIG (Metal Inert Gas) Welding

This welding process is also called Gas Metal Arc Welding. In this welding process bare electrode is used means there is no flux coating on electrode used in MIG welding. It is protected by shielding gas which are inert in nature, these shielding gasses protect electrode from air contaminants and moisture. These inert gases also protect weld joint from oxidation or any further reaction from atmospheric gases.

TIG Welding (Tungsten Inert Gas)

In this type of welding process a tungsten electrode is used. This tungsten electrode is non consumable. It is enclosed by gas atmosphere, which is inert in nature, it protects weld from reaction to air contaminants.

TIG welding became very popular technique of welding. Nowadays almost every large and small-scale industries use tis welding technique.

Carbon Arc Welding

In carbon Arc Welding Carbon electrode are used. Carbon electrode is non consumable electrode. Heat is generated between metal and electrode for welding the metal joint.

Plasma Arc Welding

As the name suggest plasma arc is used. Plasma is hot ionized gas is heated strongly it converted into plasma. This plasma produces high heat which is used to weld to melt metal.

Submerged Arc Welding

In this arc welding there uses an electrode and continuous fed electrode. In this welding an electrode is completely submerged by granular coating of flux and this flux can be electric conductor which will not oppose the electric supply.

AC Arc Welding

AC Arc welding uses transformer and don’t use rotating parts. Its transformer is comparatively less costly as compared to other metal arc welding and it uses only coated electrodes.

DC Metallic Arc Welding

DC metallic arc welding uses rotating parts, generators and motors. Its initial cost of DC set is high, and it can use any types of electrodes.

Hydrogen Arc Welding

In hydrogen arc welding arc is maintained between two non-consumable electrodes in shielding atmosphere of hydrogen gas.

Welding is an operation whereby two or more metal parts are joined by means of heat or pressure or both. Generally, only heat generation is required in welding but sometimes both heat and pressure are required to weld metal parts.

In this article, we will go through Electric Arc Welding, first, we will define Electric Arc Welding, then we will go through its types and working, at lastly we will conclude our article with applications, advantages, disadvantages, and some FAQs.
