Electron beam welding works by using a high-velocity beam of electrons to heat and melt metal surfaces, creating a strong bond when the metal cools. The key principles of electron beam welding include focusing the electron beam with magnetic fields, controlling the beam's power and speed, and using a vacuum chamber to prevent interference from air molecules.

What is electron beam lithography and how it work?
Electron beam lithography uses a focused beam of electrons to draw images on electron sensitive film. The beam changes the solubility of the film allowing the desired part to be removed by putting it in a solvent.
How does magnification occur in an electron microscope?
In an electron microscope, magnification occurs through the use of electromagnetic lenses that focus and control the electron beam. These lenses work similarly to optical lenses in light microscopes by bending and focusing the electrons to produce a magnified image of the sample. By controlling the electromagnetic fields within the lens, the electron microscope can achieve much higher magnification than a traditional light microscope.
How does the electrons microscope work?
An electron microscope uses a beam of electrons to illuminate the specimen, creating an image with higher resolution and magnification than a light microscope. The electron beam interacts with the specimen, producing signals that are used to generate a detailed image of the sample's surface or internal structure. Electrons have shorter wavelengths than visible light, enabling electron microscopes to visualize objects at a much smaller scale.
How did max knoll and ernst ruska make the electron microscope?
Max Knoll and Ernst Ruska developed the electron microscope by using a beam of focused electrons instead of light to visualize objects at a much higher resolution than traditional light microscopes. By utilizing electromagnetic lenses to focus the electron beam, they were able to achieve magnifications beyond what was previously possible with optical microscopes. Their work laid the foundation for the development of modern electron microscopy.
How does an electron microscope work to magnify and visualize objects at the nanoscale?
An electron microscope uses a beam of electrons instead of light to magnify and visualize objects at the nanoscale. The electrons are focused onto the object, creating a highly detailed image that can reveal structures as small as a few nanometers.

How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
What would cause one headlight to work on low beam and the other to work on high beam?
High beam light is out!

What is pressure welding?
In Pressure Welding the parts(work pieces) to be joined are heated only up to the plastic state and then fusedtogether by applying the external pressure.the two different types of pressure welding are:forge welding and resistance welding
What is a permanent fixing in metal work?
Welding
What is deposition rate in arc welding?
It is the rate at which the welding rod is melted and deposited on the work being welded
Can high beam work but not low beam on same bulb?
Yes
How does welding transform work?
The welding transformer - converts 'standard' mains electricity to high-amp power. The negative lead is attached to the piece of work, and the positive to the welding 'gun'. Touching the welding electrode (from the gun) - completes an electrical circuit - making an 'arc' with enough power to melt the metals together.
