guides are available identifying amperage ratings for a variety of grind angles and tip diameters. Where available, use your welding equipment manufacturer's recommendations as a starting point. In the absence of that, the information below offers some general rules of thumb to follow and may be modified according to the specific application. Basic Considerations The choice of electrode material and geometry will always be a compromise affecting the following: • shorter vs. longer electrode life • easier vs. more difficult arc starting • deeper vs. shallower weld penetration • wider vs. narrower arc and weld shape Electrode Material Different electrode materials offer various advantages in arc starting and electrode life. The following are the most commonly used electrode materials: 2% Cerium Pure Tungsten 2% Thorium 1½% Lanthanum Electrode Diameter General Formula: Diameter x 1,500 = Average amperage for acceptable electrode life (20-30 degree angle) Example: .040" diameter x 1,500 = 60 amps maximum Rule of Thumb: For a given amperage, larger diameters offer longer electrode life but may be more difficult to arc start at low amperages. Click here for more information on this topic. Angle/Taper Sharper Electrodes • less arc wander at lower amperages • more consistent arc starting • have a wider arc Blunt Electrodes • longer life • provide better weld penetration • can handle higher amperage levels Rule of Thumb: Use 20-30 angles for…

respectivas distâncias e irradiar colunas e rampas de acesso. A atividade em campo começa nivelando o equipamento no ponto inicial escolhido definindo para este ponto um referencial. Ao calar o equipamento inicia-se a coleta de dados, ângulos internos e distâncias, para fechar a poligonal, atentando-se para os detalhes a serem representados no papel. Palavras-chave: Levantamento, Planimétrico, Poligonal. ABSTRACT This survey aimed to define a polygon using only planimetric data, the…

learning to use a CAD system, lines and circles are the first two, and perhaps the most important two, geometric entities that one should master the skills of creating and modifying. Straight lines and circles are used in almost all technical designs. In examining the different types of planar geometric entities, the importance of lines and circles becomes obvious. Triangles and polygons are planar figures bounded by straight lines. Ellipses and splines can be constructed by connecting…

environmet. The nature of most DSP applications requires floating point format for data representation. While this is easy to implement on several computer systems running high level modeling software such as Simulink, it is more challenging in the hardware world due to the complexity of the implementation of floating point arithmetic. These challenges increase with portable DSP systems where more restricting constraints are applied to the system design. For these reasons Xilinx System…

sharp increase in airliner orders. One of its clients, FedEx, has placed a major order for the 747 cargo aircraft. Your supervisor has assigned you the important task of redesigning the brackets for the storage shelves on the aircraft. The new brackets need to be lighter, stronger, and more durable. You have a limited time to accomplish your assignment. You decide to use Pro/MECHANICA STRUCTURE to help you redesign the bracket. Major steps you will take through this tutorial are: …
