Power Sources for Welding Process: Both dc and ac are used for electric arc welding, each having its particular applications; in some cases either is suitable. The electric properties of the arc determines the requirements…
Electronic Control in Resistance Welding Process: As there are several factors, i.e., current, pressure, heat, time, to be considered, manual control does not yield good results in case of resistance welding. For the precise control…
Resistance Welding Machines - Overview and Circuit Diagram: Resistance welding machines incorporates a transformer, suitable electrodes for supplying current to the weld and arrangement for controlling the mechanical pressure, and finally, means for controlling the…
What is Electrodes? - Definition, Types, Applications and Advantages An electrode is a piece of wire or rod (of a metal or alloy), with or without flux covering, which carries current for welding. At one…
Laser Beam Welding - Definition, Block Diagram and Workings: Laser beam welding is a welding process that uses the heat from a laser beam impinging on the joint. The process is used without a shielding…
Electron Beam Welding - Working Principle, Advantages, Disadvantages and Applications: Basically, electron beam welding in vacuum utilises the kinetic energy of electrons travelling with high velocity in a high vacuum (10-3 to 10-5 mm Hg). When the electrons…
Ultrasonic Welding Working Principle and Applications: Ultrasonic welding is a solid state welding process that produces coalescence of materials by the local application of high-frequency (20-60 kHz) vibratory energy as the workpieces are held together…
Submerged Arc Welding - Working, Advantages and Applications: Submerged Arc Welding - It is an arc welding process that uses an arc between a bare metal electrode and the weld pool. The arc and molten…
Gas Metal Arc Welding - Working Principle, Advantages and Applications: It is a gas shielded, gas metal arc welding process which uses the intense heat of an electric arc between a continuously fed, consumable electrode…
Atomic Hydrogen Welding Working Principle and Applications: The principle of atomic hydrogen welding is based on (i) the possibility of obtaining atomic hydrogen by means of an electric arc between the two tungsten electrodes, in…
