Hi guys in this article we study the topic Advantages, Disadvantages and Applications of Resistance Welding it is important topic in welding processes so without wasting of time let's discuss further information,

Resistance welding is a type of welding process in which heat is generated by the resistance to the flow of electric current through the materials being welded. The heat generated is used to melt and join the materials together. Resistance welding is widely used in manufacturing industries for various applications.

Advantages Disadvantages and Applications of Resistance Welding

Advantages, Disadvantages and Applications of Resistances Welding

Advantages 

1) High reliability of welded joints.

2) Filler rod is not used.

3) High rate of production.

4) Less heat affected zone.

5) Not require skilled operator.

6) semiautomatic equipment's are used.

7) High reproducibility of welded joints.

8) Similar and dissimilar metals welded.

9) More economical.

10) Process takes short time.

Disadvantages

1) Proper heat balance is required.

2) Equipment cost is high.

3) More thickness parts welded is limited.

4) More electric power supply required.

5) Lower tensile strength. 

Applications of Resistance Welding

Automotive Industry: Resistance welding is extensively used in the automotive industry for the manufacture of body and chassis parts. Spot welding, which is a type of resistance welding, is commonly used to join sheet metal parts in the automotive industry.

Aerospace Industry: Resistance welding is used in the aerospace industry for the manufacture of parts and components that require high-strength welding. It is used in the fabrication of jet engines, landing gear, and other critical components.

Electrical Industry: Resistance welding is used in the electrical industry for the manufacture of electrical contacts, switches, and other electrical components. It is also used in the production of electronic devices, such as transistors, capacitors, and diodes.

Medical Industry: Resistance welding is used in the medical industry for the manufacture of medical devices and equipment. It is used to join small parts, such as wires and tubes, in the manufacture of medical devices.

Consumer Goods Industry: Resistance welding is used in the consumer goods industry for the manufacture of appliances, such as refrigerators, washing machines, and ovens. It is also used in the manufacture of furniture, toys, and other household products.

Resistance welding examples

Resistance welding is welding technique used in many industries for joining metal parts.

Spot Welding: Spot welding is the most common type of resistance welding used in the automotive industry for joining sheet metal parts together. It is also used in the manufacture of appliances, metal furniture, and other consumer products.

Seam Welding: Seam welding is used in the automotive industry for welding fuel tanks, mufflers, and other cylindrical components. It is also used in the manufacture of pipes, tubes, and ducts.

Projection Welding: Projection welding is used in the manufacture of electrical contacts, switches, and other electronic components. It is also used in the automotive industry for joining components with projections or studs, such as nuts and bolts.

Flash Butt Welding: Flash butt welding is used in the manufacture of railway tracks, construction equipment, and other heavy-duty components. It is also used in the aerospace industry for welding titanium and other high-strength materials.

Butt Welding: Butt welding is used in the manufacture of wire and cable products, such as fences, barbed wire, and electrical wiring.

High-Frequency Welding: High-frequency welding is used in the manufacture of PVC pipes, vinyl flooring, and other plastic products.
