The 4 Primary Types Of Welding and Their Advantages and Disadvantages

In layman's terms, welding is a process that combines two or more metal parts. In this fabrication, metal parts are joined together using heat and pressure to form a joint between two parts as their temperature decreases. The heat transfer on the metal's surface melts the two pieces to join them as one piece.

The welding process is fundamental in every industry today, and a highly skilled
poly welder is needed for quality work. Although welding is preferable for metals and thermoplastics, it can also join the wood pieces. But here, we are discussing welding techniques for metal only.

Arc Welding:

It is one of the most fundamental types of welding. An electric arc is created between the base metal and electrode to melt the point of contact on the metal. The welder uses an electric arc to join metals through heat during this process. These types of welding are mainly used in Shipbuilding, Automotive, Construction, and Mechanical industries.

Advantages of Arc welding:

• High-speed welding process
• Simple welding equipment
• Portability
• Work on AC or DC
• High temperatures

Disadvantages of arc welding:

• Not suitable for thin metals
• Requires skilled welders
• Not usable for Aluminum or Titanium

MIG Or Metal Inert Gas Welding:

This method uses an eclectic arc to weld two metal pieces. A solid electrode wire is used to melt two base materials to form a joint. The electrode wire is attached to a welding gun to create heat. This method is used for joining two different metals. The is Used is sheet metal welding, pressure vessels and steel structures fabrication. Automotive and home improvement industries are the two primary industries for this welding technique.

Advantages of MIG welding:

• High-quality welds
• Minor weld splatter
• Join dissimilar metals
• Fully or semi-automatic
• Good weld speed

Disadvantages of MIG welding:

• Suitable for thin metals
• Unsuitable for outside welding
• Needs metal preparation

TIG Or Tungsten Inert Gas Welding:

This welding technique uses an electrode (non-consumable tungsten electrode ) to create an arc between two metals. Inert gasses create a shield to protect the weld area and electrode from oxidation and other atmospheric contamination. TIG welding can be used for various metals, including magnesium, copper, copper, nickel, aluminium, and titanium. The TIG technique is primarily used in the Automotive industry for Auto body repairs and In Aerospace and aircraft construction.

Advantages of TIG welding:

• Clean welds
• A high degree of welding
• Use filler material
• Manual or automatic methods
• Strong welds

Disadvantages of TIG Welding:

• Time-consuming
• Needs skilled welders
• Suitable for thin metal joints

Flux-cored Arc Welding Or FCAW:

This welding technique needs a constant-voltage power supply through electrode wire to weld two metal pieces. This welding technique is used in Manufacturing plants, Shipbuilding, Industrial piping, Railroad maintenance and repair. Two types of Flux-cored Arc Welding are Self-Shielded and Gas-Shielded Flux-Cored welding. These different methods are defined through the shielding process of the weld calculator.

Advantages of flux cored arc welding:

• Excellent weld penetration
• Suitable for thicker joints
• Flexible movement and orientation
• The high metal deposition rate

Disadvantages of flux cored arc welding:

• Slag inclusion
• Expensive
