What Is Resistance Welding?

Resistance Welding is a type of metal joining process (or type of welding) that uses pressure and electrical resistance to weld (or join) the two thin metal pieces. The resistance welding works purely on electricity. The resistance welding does not require any joining or filler metals and even the arc is not developed during the welding process. In some cases, the resistance welding uses hydraulic pressures (or manual) in the joining process.

Resistance Welding, Types Of Resistance Welding, Its Advantages And Applications

The current supplied to the resistance welding will be converted to heat energy (or thermal energy) and it will flow through the electrodes of the welding. The sheet metals that to be joined will feed into the two electrodes and due to this contact; the sheet metals will be welded (or joined). The amount of heat generated (or required) in the resistance welding process can be given as

  • H – Amount of Heat Generated
  • I – Current Flow (in Amperes)
  • R- Resistance (in ohms)
  • T = time for current flow (in seconds)

What can you learn from this post?

  • Types of resistance welding
  • Advantages of resistance welding
  • Applications of resistance welding
  • Conclusion

Let us start with types of resistance welding.

Types of resistance welding:

There are different types of resistance welding according to their way of welding the metals, and their usage of parts. Here are the main available types of resistance welding:

These are the main types of resistance welding that we can see in industries or some other places. You can read about these types of resistance welding in detail in upcoming posts.

Advantages of resistance welding:

The advantages of resistance welding are very notable and unique when compared to the other types of welding. The advantages of resistance welding will be varying according to types of resistance welding. The few and main advantages of resistance welding are

  • The resistance welding can join the thin sheet materials without using any arc.
  • The usage of electricity and easy operation is other main advantages of resistance welding.
  • The construction of the resistance welding process is easy.
  • No gas or filler materials are required to perform the operations.
  • The main advantages of resistance welding are that the operation is faster and quicker when compared to other types of welding.
  • The joining of the dissimilar metals is another added advantages of resistance welding.
  • The heat developed in this type of welding does not lead to any life-risk accidents.

Applications of resistance welding:

The applications of resistance welding are

  • The applications of resistance welding mostly available in the Automobile Industries to join the thin sheets.
  • The boiler sheets and leakproof materials will be welded with resistance welding which is a unique and different type of applications of resistance welding.
  • Resistance welding is used in large production industries.
  • The applications of resistance welding are frequently found in pipe joining Industries or workshops.

Conclusion:

The resistance welding and types of resistance welding are totally different and unique to the other types of welding like arc welding, and gas welding. If we observe, all types of resistance welding will not produce any arc and gas in its joining process. Due to the production of only heat in resistance welding, it can be chosen for large productions and high field applications. The resistance welding parts are simple and do not contain any heavily weighted devices too.
