Projection Welding
Projection welding is like spot welding separated from a dimple can be generated on work parts at the spot any place weld is liked. At present the work parts held among cathode as well as a gigantic amount of current course through it. A little amount of strain can be applied all through the cathode on welding safeguards. The progression of current all through dimple which disintegrate it and the power reasons the dimple level and shape a weld.
Advantages of Projection Welding
- There is no limitation on the metal thickness, i.e., metal of any thickness can be welded with the projection welding.
- Multiple welds can be made at once with projection welding. Subsequently, more result is acquired.
- In the projection welding, less current is gone through the terminals and low strain is applied. Hence, the anode life is expanded.
- Projection welding gives great intensity balance while welding process.
- The projection welding method results in a weld with a polished appearance.
Disadvantages of Projection Welding
- The course of projection development is complicated and time consuming.
- It requires highly skilled welders.
- Projection welding can’t be applied to a wide range of workpieces.
- Hardware utilized for projection welding are costly.
Applications of Projection Welding
- Projection welding is used for welding studs, nuts to plates, etc.
- Projection welding is also used in the shipbuilding, automotive, and sheet metal industries.
- It is moreover used for welding the bits of cooler, condensers, etc.
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.
