Electric Welding: Types & Advantages

Electric Welding

The process of joining materials together through the use of heat that is produced by an electric current is known as electric welding.

Electric welding is often done by melting the workpieces by the heat produced by electric current and adding a filler material to form a pool of molten material that cools to become a strong joint.

In other words, the branch of welding in which electric current is used to produce the large heat required for joining of pieces of metals together is called the electric welding.

The electric welding is gaining acknowledgement, because of its machinery is inexpensive and easy manipulation becoming known.

Types of Electric Welding

The electric welding process is classified into two categories, viz −

  • Arc Welding

  • Resistance Welding

Arc Welding

Arc welding is the type of electric welding process in which two metals are joined through the heat that is produced by an electric arc.

Electric arc welding can be further classified into following types −

  • DC Metallic Arc Welding

  • AC Metallic Arc Welding

  • Carbon Arc Welding

  • Atomic Hydrogen Arc Welding

  • Shielded Arc Welding

Resistance Welding

Resistance welding is the process of joining two metal work pieces together by passing an electric current for a length of time through the metals to be joined and a mechanical pressure is also applied for joining the metal workpieces.

The resistance welding is also classified into following types −

  • Butt Welding

  • Flash Welding

  • Spot Welding

  • Seam Welding

  • Projection Welding

Advantages of Electric Welding

Some of the advantages of the electric welding processes are given as follows −

  • Electric welding is suitable for high speed welds.

  • Electric welding apparatus are simple and portable.

  • Electric welding can produce superior temperature as compared other types of welding processes.

  • Automatic welding is possible with the electric welding.

  • Welds obtained are very clean.

  • Electric welding creates strong welds.
