RESISTANCE WELDING
RESISTANCE WELDING
What is resistance welding?
According to AWS, Resistance welding is the joining of metals by applying pressure and passing current for a length of time through the metal area which is to be joined.
Resistance welding is a widely used welding technique that involves the application of heat and pressure to join two metal pieces together. This welding process is commonly used in various industries, including automotive, aerospace, and electronics, to manufacture different parts and components.
The process of resistance welding is quite straightforward. It involves applying pressure to two metal pieces that are placed between two electrodes. An electric current is then passed through the electrodes, generating heat that melts the metal pieces at their contact points. The heat generated by the current causes the metal to liquefy, and the pressure applied by the electrodes helps to forge the pieces together.
Resistance welding is a very efficient welding process that results in high-quality welds. It is also a fast process that can be automated, resulting in higher productivity and reduced labor costs. This makes it a popular choice for mass production industries.

ADVANTAGES OF RESITANCE WELDING
- One of the main advantages of resistance welding is its precise heat control, which enables welds of consistent quality to be produced. The welds produced by resistance welding are also stronger than other types of welds, which makes them an ideal choice for applications that require high-strength joints.
- Another advantage of resistance welding is that it can be used to join dissimilar metals, which means that it is possible to weld together materials with different thermal properties or melting points. This makes resistance welding a versatile process that can be used in a variety of applications.
DISADVANTAGES OF RESITANCE WELDING
- One of the primary limitations is that it can only be used for joining metals that are conductive. This means that it cannot be used to weld non-metallic materials like plastics or ceramics.
- Additionally, resistance welding is not suitable for materials that are too thin, too thick, or too large for the welding equipment.
CONCLUSION
In conclusion, resistance welding is an efficient welding process that has found widespread use in various industries. Its advantages include its precise heat control, strong welds and ability to join dissimilar metals, while its limitations arise from its inability to weld non-conductive materials and materials that are too thin, too thick, or too large. Despite its limitations, resistance welding remains an important and valuable welding process for industrial applications.
