What is Resistance Welding ? Uses and Working

Resistance Welding

Resistance welding is a process of joining metals by applying pressure and electric current to the materials. This effective method of welding has been used for decades in various industries, including automotive, aerospace, electrical, and plumbing. Let’s take a closer look at resistance welding and how it works.

What is Resistance Welding?

Resistance welding is a fusion process that uses heat generated from electric resistance to joining two or more metal parts. The metal parts are brought together under pressure; an electric current is passed through them for a few milliseconds until the metal reaches its melting point. The intense heat generated by passing electricity through the metal causes the pieces to fuse together without having to add any filler material, such as solder or flux. It’s important to note that the process should be done quickly to avoid damaging the material.

 Resistance Welding Uses

Resistance welding has many applications in various industries today. It can be used for joining sheet metals, wire mesh, pipes, tube sheets, rods, and more. In addition, it can also be used to form various shapes like rivets and studs with precision and accuracy. It also offers excellent strength and reliability due to its high-temperature joining capabilities. As such, it’s widely used in manufacturing processes for products such as automobiles, aircraft components, electronic equipment, home appliances, plumbing fixtures, etc.

How Does Resistance Welding Work?

The basic principle behind resistance welding involves applying electric current between two pieces of metal while simultaneously pressing them together with force until they reach their melting points simultaneously. The amount of pressure applied will determine the quality of the weld achieved; too little pressure will result in weak joints, and too much pressure could cause excessive distortion due to heat build-up in localized areas on the welded part. A good rule of thumb when using resistance welding is “less is more”—just enough force should be applied to achieve your desired results without causing any damage or distortion to the part being welded.


Resistance welding is an efficient and reliable way of joining metals without using additional filler material like solder or flux. This process requires precise control over pressure and current levels to achieve optimal results without damaging the materials being joined together. By understanding how this process works and how it can help you improve your manufacturing processes, you’ll be able to make better-informed decisions about which welding technique best serves your needs going forward!
