Tungsten Many practical applications of Tungsten are based on its high melting point and density and its low vapor pressure. Tungsten is an excellent material for high vacuum technology, dimensional stability, glass seals and furnace construction. In addition, Tungsten’s high density gives it a .

Tungsten-Thorium Oxide alloys are generally safe to handle during use under all normal conditions and environments. However, special precautions must be taken during the grinding or machining of tips of electrodes that contain Thorium Oxide to avoid the generation and subsequent inhalation andFile Size: KB. Radiograph Interpretation - Welds. In addition to producing high quality radiographs, the radiographer must also be skilled in radiographic interpretation. Interpretation of radiographs takes place in three basic steps: (1) detection, (2) interpretation, and (3) evaluation. All of these steps make use of the radiographer's visual acuity.

CHOOSE ELECTRODES FROM A TRUSTED SOURCE Although tungsten electrodes may look the same from one company to another, high-quality tungsten has been manufactured to ensure a dense grain structure which allows for better migration of oxides to the tip of the electrode. generated in the form of Instructional Media Packages (IMPs). An IMP consists of Theory book, Practical book, Test and Assignment book, Instructor Guide, Audio Visual Aid (Wall charts and Transparencies) and other support materials. The trade practical book consists of series of exercises to be completed by the trainees in the workshop.
