Setup for Laser Welding (With Diagram) | MetallurgyThe most useful laser for welding is the CO 2 laser in which the lasing medium is a mixture of CO 2, nitrogen, and helium in the ratio of 1: 1: 10 at a pressure of 20 to 50 torr (mm of mercury) with an electrical discharge of upto 30,000 volts. A CO 2 laser can operate continuously with an output of upto 20 kw.
Laser Beam Machining (LBM) is a non-traditional, computer numeric controlled. machining process which is being used to machine a large variety of materials. having intricate shapes, with high levels of accuracy and high quality surface finish. that is difficult to attain with conventional machining processes. From last forty.
The various main parts used in the laser beam machining are. 1. A pumping Medium: A medium is needed that contains a large number of atoms. The atoms of the media are used to produce lasers. 2. Flash Tube/Flash Lamp: The flash tube or flash lamp is used to provide the necessary energy to the atoms to excite their electrons.
Cutting through the metals and other materials for getting the desired product. The process of laser beam machining uses the thermal energy of the laser to cut, Heat and vaporize the materials in use or question. This process finds its best application in carving out things. From brittle materials with low conductivity.
A laser beam machining is a non-conventional machining method in which the operation is performed by laser light. The laser light has maximum temperature strikes on the workpiece; due to high temp, the workpiece gets melts. The process used thermal energy to remove material from a metallic surface.
A laser beam machine according to this invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional diagram showing the machining head of a laser beam machine, a first embodiment of the invention.
Laser Beam Machining (LBM) A high intensity beam of focused electrons is used to supply heat for material removal. A high intensity beam of laser (coherent photons) is used to supply heat for material removal. EBM process is always carried out in vacuum (very low pressure) chamber to avoid collision of electrons with air molecules.

Electron Beam machining or EBM is a non-conventional machining process, Where the electrons are focused and concentrated on a small spot on the metal, the kinetic energy of the electrons is converted into heat energy which is sufficient to melt the workpiece, Known as Electron beam machining or EBM. It is just similar to laser beam machining ...
A laser cutter is a prototyping and manufacturing tool used primarily by engineers, designers, and artists to cut and etch into flat material. Laser cutters use a thin, focused laser beam to pierce and cut through materials to cut out patterns and geometries specified by designers. Apart from cutting, laser cutters can also raster or etch ...

Working of Laser beam machining 1) When the high voltage power source is on, Xenon lamps start producing light. 2) The electrons in the crystal atoms starts absorbing the light from the xenon lamps. 3) Due to light, Electrons get energized to a high energy level from the ground state & start emitting more photons with comes to the ground state.
Process Capability. Laser beam machining process Laser beam machining process uses highly coherent light source. This beam can be focused by means of a lens on a very small spot in the work piece. The high power radiation of laser gives rise to high temperature on a small area of work piece. This initiates the cutting process in the work material.
Laser beam machining is a form of the machining process in which laser beams are used for the Machinings of metal and non-metallic materials. In this process, laser beams of high energy are created to strike the workpiece, the thermal energy of the lasers is transferred to the surface of the W/P (workpiece).
Profile cutting and slitting in hard materials can be done using this method. Laser beam machining. A laser is an electromagnetic radiation source. A beam of the same wavelength is focused by a lens on a very small spot on a work piece. The laser beam emits high heat, which can melt and vaporize any type of material.

Laser Beam Welding (LBW) is a welding process, in which heat is generated by a high energy laser beam targeted on the workpiece. The laser beam heats and melts the edges of the workpiece, forming a joint. The energy of a narrow laser beam is highly concentrated at 10 8 -10 10 W/cm 2, so a weak weld pool is formed very rapidly (for about 10 -6 sec).
