Flash Butt Welding
Flash butt welding is a type of resistance welding that is used in the steel industry to weld both tubes and rods. In this strategy, two work parts are welded which will be held tightly during the terminal holders as well as a high pulsed flow of current inside the 1,00,000 ampere range can be provided toward the work part material.
In the two electrode holders, one is long-lasting and other is variable. At first, current can be supplied, and a spark will be produced when the changeable clamp is pressed against the permanent clamp due to contact between the two parts at high current. At the point when the edge surface methodologies into plastic shape, the progression of current will be halted too as hub power can be improved to make joint. Due to plastic deformation, the weld can be formed using this method.
Advantages of Flash Butt Welding
- It is a faster process.
- Preparation of weld surface isn’t needed.
- Power necessity is less.
- Numerous dissimilar metals with various melting temperatures can be flash welded.
- The process is cheap.
- It offers strength factor up-to 100 percent.
Disadvantages of Flash Butt Welding
- More possibilities of fire hazards.
- Metal is lost during flashing and disturbing.
- Concentricity and straightness of the work pieces during welding process is frequently challenging to keep up with.
Applications of Flash Butt Welding
- It is utilized for welding metal sheets, bars, rods fittings and so on.
- Flash welding finds applications in car and air craft products.
- It is additionally utilized in home devices, coolers and farm implements.
Electric Resistance Welding
In the past days, the process of metal welding should be possible by heating the metals and pressed jointly which is known as the forge welding method. In any case, as of now, the welding innovation has been changed by the arrival of electricity. In the nineteenth century, resistance, gas, and arc welding was invented. After this, there are various types of welding technologies have been imagined like friction, ultrasonic, plasma, laser, and electron beam welding. However, the uses of welding technology essentially include different industries.
