Jan 01, 2018· Laser cutting is used for extreme precision. The laser beam is typically 0.2 mm in diameter with a power of 1-10 KW [14]. Laser beam cutting is a two dimensional (2-D) LBM process which is performed by providing relative motion between laser beam and the sheet material surface. Figure 1 Systematic representation of a CO2 laser setup [14] Figure .2.
The divergence of the beam is more than 125 to 400 milliradians which is greater than other laser types. The output beam has an unusual shape as the medium used is short and rectangular. The working of this laser type is dependent on the temperature. Stay tuned to learn more about other concepts of Physics.
The main differences between the two are the heat sources used to melt the powder. Take a deeper look into laser and electron beam powder bed fusion: 1. Laser Powder Bed Fusion.

The laser beam produced is focused on the workpiece that has to be machined. When the laser strikes the workpiece, the thermal energy impinges on the workpiece. This will heat then melt, vaporize, and finally, the material will be removed from the workpiece. So laser machining is a thermal material removal process that uses a coherent beam of ...

Delivered by 192 UV laser beams at Lawrence Livermore National Laboratory’s National Ignition Facility, the 1.85 MJ of energy struck a target that was just 2 mm in diameter. The energy level enabled the study of states of matter such as those ...
Apr 14, 2017· Electron beam welding is a liquid state welding process. Liquid state welding are those welding processes in which, the metal to metal joint form in liquid or molten state. This is also classified as a new welding process because it uses electrons kinetic energy to fuse two metal work pieces. This welding is developed by the German physicist ...

Electron beam (EB) welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. The beam of electrons creates kinetic heat as it impacts with the workpieces, causing them to melt …

The process variables are: 1. Accelerating Voltage 2. Beam Power 3. Beam Spot Size 4. Welding Speed. Process Variable # 1. Accelerating Voltage: With the increase in accelerating voltage, the penetration of the weld Increases. High voltage system (70-150 Kv) allows finer spot sizes, longer focal length and greater working distances.

Apr 08, 2021· The principle of plasma arc machining is shown in the figure. In a plasma torch, known as the gun or plasmatron, a volume of gas such as H2, N2, 02, etc. is passed through a small chamber in which a high-frequency spark (arc) is maintained between the tungsten electrode (cathode) and the copper nozzle (anode), both of which are water-cooled.
Mar 07, 2012· Laser-engineered net shaping (LENS) technology was jointly conceptualized by Sandia National Laboratories and Pratt & Whitney and then licensed to Optomec, Inc., during 1997 [31] (US Patent 6046426, 2000). A schematic of this process is shown in Fig. 2.8.Unlike in SLM, which has a powder bed, the component is manufactured using the LENS technique by …
Alignment lasers can have different shapes of the output beam. The most common ones are the following: Spot lasers (or dot lasers) are used for marking a single spot.; Line lasers emit beams which are substantially elongated in one direction, projecting narrow straight lines. Here, the opening angle is an additional important parameter.
