Spot Welding
The simplest form of welding is spot welding, in which the workpieces are held together by the anvil face’s force. The copper (Cu) terminals will connect with the work segment and the progression of current through it. The work portion material applies a couple of protections inside current stream which will cause restricted heat creation. The opposition is high at the edge surfaces on account of the air gap. The current starts to supply through it, then, at that point, it will decrease the edge surface.
The current supply and the time should be enough for the right dissolving of edge faces. Presently the progression of current will be halted anyway the power applied with terminal went on briefly, while the weld immediately cooled. However, the terminals take out as well as reach out to new detect to make a round piece. The piece size predominantly depends upon electrode size (4-7 mm).
Advantages of Spot Welding
- Spot welding has high similarity with effectiveness and consistency.
- Spot welding is economical.
- Spot welding gives a significantly more efficient approach to using electrical energy for welding process.
- Spot welding is a quick welding process.
Disadvantages of Spot Welding
- Spot welding requires an large working area.
- Spot welding uses a heavy welding gun that requires a lot of strength to operate. Subsequently, spot welding might be extremely hazardous to the matured welders.
- The thicker materials are not suitable for spot welding.
Applications of Spot Welding
- Spot welding is utilized in different ventures, for example, auto, aviation, metal furnishings, hardware, building development, and so on.
- Spot welding is utilized in high volume creation applications.
- It is used to weld thin sheets together.
- Spot welding is likewise utilized for manufacturing a wide range of sheet metal designs where high mechanical strength is required.
- Spot welding can likewise be applied to a wide range of boxes, centers and encasing cases, and so on.
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.
