Book excerpt: El presente libro es una adaptación de una investigación presentada a la Universidad Nacional del Altiplano en la cual se estudió la resistencia a la dureza del acero inoxidable austenítico AISI 304 mediante un estudio comparativo de los procesos de soldadura SMAW y GTAW para unir planchas de 8.0 mm de espesor con una junta a tope en V y en posición plana 1G. Se determinó los parámetros de operación adecuados, siendo este uno de los objetivos del estudio, para luego establecer cuál de los procesos con uniones soldadas presenta óptimas propiedades mecánicas de resistencia adecuada de dureza en la zona afectada por el calor. Se utilizó la metodología del tipo experimental y aplicada, una vez obtenidas las juntas soldadas primeramente se realizó una inspección visual, seguido de un barrido de dureza con escala Rockwell B aplicada en zonas cercanas a la soldadura, considerándose la norma AWS D1.6 como referencia para establecer los criterios de aceptación de los ensayos realizados. Los datos obtenidos se tabularon, se procedió a la selección del mejor material de aporte, mediante un análisis adecuado con la finalidad de determinar cuál presenta una mejor influencia en las propiedades de dureza del acero inoxidable austenítico AISI 304. Los resultados que se obtuvieron demuestran que utilizando el proceso de soldadura GTAW con varilla ER308L, es más eficiente para unir el acero AISI 304 frente al proceso SMAW utilizando electrodo E308L-16, debido a que la soldadura GTAW proporciona soldadura limpia de escoria, son de gran calidad al tener siempre protegido el área de la soldadura de la atmósfera y presenta mayor resistencia a la dureza en la ZAC de 99.5 HRB frente al proceso de soldadura SMAW que tiene 98.0 HRB de resistencia a la dureza; así mismo se contribuye a mejorar los procedimientos de soldadura en este tipo de material que pueden ser aplicados en el campo industrial de la metalurgia transformativa.

Book Synopsis Evaluación y comparación del desgaste corrosivo a altas temperaturas en los aceros inoxidables austeníticos, AISI - SAE 304H, AISI - SAE 316L y acero al carbono 1020 by : Jayson Diomer Moreno Franco
Download or read book Evaluación y comparación del desgaste corrosivo a altas temperaturas en los aceros inoxidables austeníticos, AISI - SAE 304H, AISI - SAE 316L y acero al carbono 1020 written by Jayson Diomer Moreno Franco and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: La transformación de energía térmica en mecánica o en cualquier otra forma de energía, hace que la eficiencia aumente cuanta más alta sea la temperatura a la que se lleva a cabo la transformación. Esta es la causa de que se pretenda trabajar en condiciones extremas con el fin de ahorrar combustible. Esta tendencia se ve limitada por la respuesta de los materiales bajo estas condiciones a altas temperaturas. Las condiciones corrosivas provocan en muchas ocasiones la falla de los materiales y por consiguiente la salida de servicio de las unidades de proceso de las que forman parte. Las fallas en los materiales que han sufrido una degradación metálica por corrosión de alguno de sus componentes suponen altos costos de mantenimiento, debido a paradas no programadas, dando como resultado sensibles disminuciones de la productividad de los equipos; además la corrosión de las superficies de transferencia de calor en sistemas de combustión es el mayor obstáculo para incrementar la eficiencia térmica de la combustión en planta, debido a que el ataque por corrosión a alta temperatura de una aleación causa una disminución del espesor y a su vez disminuye la transferencia de calor por el carácter aislante del depósito. Los aceros AISI - SAE 304H y AISI - SAE 316L son utilizados para la construcción de supercalentadores, recalentadores, paredes y tuberías de caldera; estos componentes son altamente sensibles al desgaste corrosivo a altas temperaturas, causado por el depósito de sales fundidas o cenizas de aceite en fase líquida. Haciendo uso de los laboratorios que posee la Facultad de Ingeniería Mecánica de la Universidad Tecnológica de Pereira, se emplearon técnicas gravimétricas para evaluar la tendencia en el comportamiento de los aceros austeníticos AISI - SAE 304H, AISI - SAE 316L y acero al carbono 1020 que estuvieron en contacto directo de una mezcla compuesta de 80% V2O5 (Pentóxido de Vanadio) y 20% Na2SO4 (Sulfato de sodio), a temperaturas de 700°C.

Download or read book Fracture and Fatigue of Welded Joints and Structures written by K Macdonald and published by Elsevier. This book was released on 2011-04-19 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents. Fracture and fatigue of welded joints and structures analyses the processes and causes of fracture and fatigue, focusing on how the failure of welded joints and structures can be predicted and minimised in the design process.Part one concentrates on analysing fracture of welded joints and structures, with chapters on constraint-based fracture mechanics for predicting joint failure, fracture assessment methods and the use of fracture mechanics in the fatigue analysis of welded joints. In part two, the emphasis shifts to fatigue, and chapters focus on a variety of aspects of fatigue analysis including assessment of local stresses in welded joints, fatigue design rules for welded structures, k-nodes for offshore structures and modelling residual stresses in predicting the service life of structures.With its distinguished editor and international team of contributors, Fracture and fatigue of welded joints and structures is an essential reference for mechanical, structural and welding engineers, as well as those in the academic sector with a research interest in the field. - Analyses the processes and causes of fracture and fatigue, focusing predicting and minimising the failure of welded joints in the design process - Assesses the fracture of welded joints and structure featuring constraint-based fracture mechanics for predicting joint failure - Explores specific considerations in fatigue analysis including the assessment of local stresses in welded joints and fatigue design rules for welded structures

Book Synopsis Building Wireless Community Networks by : Rob Flickenger
Download or read book Building Wireless Community Networks written by Rob Flickenger and published by "O'Reilly Media, Inc.". This book was released on 2003 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
