Advantages and disadvantages of riveted joints, Advantages and disadvantages of solid fuels, Advantages and disadvantages of liquid fuels, Difference between electrochemical series and galvanic series, Difference between rigid and flexible coupling, Full Form of Education Degree and Related Terms. Orthovoltage (low energy) x-rays can effectively treat recurrent cutaneous lymphoma lesions, but its penetration to underlying tissues (blood vessels, muscles, bone marrow) is a disadvantage if the disease is widespread.In contrast, electron beam therapy delivers radiation primarily to the superficial layers of the skin. A proton beam can be directed so that the Bragg Peak occurs precisely in the tumor volume. It can cut drill holes or cut slots which otherwise cannot be made.Disadvantages of electron beam machining : High equipment cost. Our objective – satisfied customers worldwide. Electron beam welding is used in a wide range of applications from welding films to large work pieces over 200 mm thickness. The electron beam (=EB) is a universal tool for processing metallic materials by electron beam welding, EB drilling and electron beam surface treatment and has been used in industry for many years. Specialist for chamber machines designed for welding and drilling purposes. What is electron beam melting? No cutting tool pressure or wear occurred in this process. 10 advantages of electron beam welding Since we started this blog a few months ago, we’ve written about a lot of topics related to laser welding, which hopefully you’ve found useful. External beam radiation therapy is where the radiation is directly aimed at the cancer cell area. Electron beam machining is processed by a high-velocity focused stream of electrons which heats, melts and vaporizes the work material at the point of bombardment thus metal will be removed. It is distortion free-machining so precise dimensions can be achieved. Avoidance for reworking and corrections (minimum distortion), Abdication of filler material and shielding gas, New ways in design and production planning enables improvements in existing and realization of completely new products, Very small heat affected zones without tarnishing effect. After that, a potential difference is applied across the tungsten filament so … It provides a targeted beam of radiation to an affected area so that damage to healthy tissues can be minimized. Almost all work parameters are controlled electronically and can be easily adjusted to changed tasks. It would therefore be possible in a single process to use the electron beam to look for the weld joint ahead, to weld the work piece using the correction values, and to finish by cosmetically treating of the weld. Proton therapy also can be precisely targeted to the exact depth of the tumor, minimizing damage to other parts of the body. Proton therapy: Targets tumors and cancer cells … What are the advantages? The pros of proton therapy for cancer include that it is more accurate than alternative treatments and less likely to cause damage to surrounding tissues. I have been diagnosed with prostate cancer . Is proton beam therapy the right treatment for prostate cancer? The main objective is to connect all mechanical engineering people all over the world. EB welding and drilling technology was introduced to industry many years ago as a reliable means of fabrication. Radiation therapy is one of the many therapies available as of 2011 to battle cancer 1 2 3.Radiation therapy uses high-energy doses of radiation to destroy cancer cells 2.It is often used in conjunction with other treatments, including surgery and chemotherapy, to destroy cancer cells. For a small number of people with borderline resectable cancer and locally advanced pancreatic cancer, radiotherapy may help to make surgery possible. The dose immediately beyond the Bragg Peak is essentially zero, which also spares normal tissue distal to the tumor volume. Electron Beam Welding is a liquid state welding process in which two similar or dissimilar metals are joined by the use of heat and that heat is generated by high energy electrons. Proton beam therapy 1. So, it is also possible to weld a suitable work piece „quasi-simultaneously" at several places. In this machining, metal is removed from workpiece by melting and vapourizing of metal particles in a controlled from its surface using heat from laser. The possible role of electrons in treating the post-mastectomy chest wall is considered in greater detail with particular reference to the potential danger of post-radiation fibrosis in the lungs. Rigid coupling some cases called sleeve or muff coupling are economical and mostly designed for the aligned sh... Galvanizing is an iron or steel sheet coating process with a thin zinc coat to avoid rusting.

Side effects typically seen with X-ray therapy, both acute and long-term, can be markedly reduced with proton therapy. The Christie is the first NHS high-energy proton beam therapy centre in the UK as part of a £250m programme for a national proton beam therapy service. With electron beam welding, excellent metallurgical results are achieved without harmful emissions in the vacuum of the electron beam chamber, which is at a pressure of 5 x 10-4 mbar. Premium Questions. The technique and dosage are described and discussed. Electron beam welding (EBW) is a metal welding technique which takes place in a vacuum chamber using a beam of high energy electrons to heat the metal. Relieve your resources and increase your efficiency! An extremely fast electron beam deflection makes other applications possible, which could only be done with difficulty, if at all, using another welding method. The treatment can cause the same side effects as other forms of radiation treatment, however, and also is expensive. Parts and subcomponents that require a high level of mechanical pre-processing can be joined using this method without being damaged due to the low angular distortion and the minimal cross-sectional shrinkage. When an electron strikes with a high speed to the workpiece there are two forms of energy conversion that take place kinetics energy and thermal energy. Titanium is usually done under a (expensive) shielding gas atmosphere. Mechanicalfunda.com is a Mechanical Engineering oriented platform run by Jay Solanki who is a B-Tech Graduate in Mechanical Engineering from NIT and currently pursuing MBA from Symbiosis International University. Consequently, it shows many advantages over x-ray therapy. Just as with traditional radiation (x-ray/IMRT), protons treat tumors by directing radiation into the tumor site, where doses of radiation destroy cancerous cells. Electron beam welding is used for joining metallic materials. The main advantages and disadvantages of electron therapy in these situations are discussed. Working of Electron Beam Machining: At first, a vacuum is created and maintained using the diffusion pump within the electron beam chamber. ... What are the advantages and disadvantages of radiology ?
