This book was released on 2012 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite abundant evidence for the adverse health effects associated with welding fume, shipyard welders continue to have exposures that routinely exceed safe limits. Welding in shipyards can be particularly hazardous due dynamic conditions and work in enclosed and confined spaces. Currently, there are no specific ventilation guidelines available to shipyard welders, beyond general regulatory requirements for local exhaust and general dilution air flow rates. In this study, general ventilation guidelines were developed for inclusion in a training intervention. Using an observational tool based on those guidelines, a baseline characterization of the work practices and use of ventilation in enclosed and confined space welding tasks was performed at a Seattle shipyard. To assess ventilation effectiveness, a scoring system was developed to compare actual and recommended ventilation practices. Comparing ventilation techniques and estimated exposure suggests that adoption of the intervention guidelines reduces the potential for welding fume exposure. Additionally, an inter-observer assessment based on side-by-side field measurements shows good agreement for the observational behavior tool, establishing the method as a reliable way to detect a change in ventilation-related behavior post-intervention.

Download or read book The Welding Workplace written by R Boekholt and published by Woodhead Publishing. This book was released on 2000-02-11 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The welding industry is in the process of change and under pressure. New processes and new materials are being introduced in the wake of increasingly tough competition. In this book, Richard Boekholt, a senior welding consultant with vast experience and a uniquely international outlook, has compiled and summarised international practice within the field of welding developed from a European Union study 'Working Life 2000. The Welding Industry in Technological Change: a Human Resource Perspective'. The book looks at the impact of automation and explains that, while some people may feel that the use of robotics and computers will threaten welders' jobs, in fact robots and computers will help welders, not replace them. At present welders are in demand and companies are faced with difficulties in recruiting and retaining good staff. It is through improved working conditions, which are presently often environmentally unsafe with workers exposed to smoke, noise, vibration and heavy physical labour, that companies can attract and keep workers. The book emphasises the importance of managing human resources and looks at new ways of doing this. A recognition of the importance of managing human resources and looks at new ways of doing this. A recognition of the importance of training, of instructors as well as workers, will be essential to achieve the dedicated, motivated and flexible workforce necessary to work with the new technologies of the 21st century.

This book was released on 2009 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past twenty-five years, the United States shipbuilding industry has experienced a slow decay in both hiring and retaining critical skilled professionals. One of the most critical skills required to fabricate a ship is welding, as welders play a major role in shipbuilding, from pre-fabrication to delivery. Many factors can be identified with the cause of this reduction in the welder workforce. These factors include technology enhancement, outsourcing, growth of optional career opportunities, and family pressure. The latter factor is identified as playing a role in reducing initial accessions within the Department of Defense. Military recruiters have been required to alter their tried and true recruitment strategies. Parents, who do not wish to see their children subjected to the violence of war or to serve within, what they perceive, as a low return on investment career, are pushing their children away from military service in favor of continued education or careers in the private sector. This phenomenon is not unlike the pressures that potential welders receive from their own families. Shipbuilding is a demanding profession, requiring a level of mental and physical toughness not necessarily found in most manufacturing industries. Under the best conditions, commercial welding is challenging; it requires manual dexterity and mental visualization skills as well as years of experience. Given the existing conditions in most shipyards, marine welding is even more challenging. These skilled craftsmen work in hot, tight, poorly-lit spaces, often working around corners with no clear line of sight to their work. Yet, the expectations of first-time, "perfect" quality is a hard requirement. For years, shipyards around the country relied upon third- and fourth-generation welders to replace their ranks caused by attrition. But due to the factors presented, these companies must employ new strategies to combat losses in its workforce. One such strategy is to better define requirements traceable to period and cumulative scope of work, and to formulate a more responsive organizational structure to meet this need so that the right number and the right skill sets can be targeted for recruiting and retention goals. This thesis identifies attributes within military organizations that could aid in the development of a similar organizational model for use in shipbuilding.

Download or read book Ship Construction and Welding written by Nisith R. Mandal and published by Springer. This book was released on 2016-11-09 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses various aspects of ship construction, from ship types and construction materials, to welding technologies and accuracy control. The contents of the book are logically organized and divided into twenty-one chapters. The book covers structural arrangement with longitudinal and transverse framing systems based on the service load, and explains basic structural elements like hatch side girders, hatch end beams, stringers, etc. along with structural subassemblies like floors, bulkheads, inner bottom, decks and shells. It presents in detail double bottom construction, wing tanks & duct keels, fore & aft end structures, etc., together with necessary illustrations. The midship sections of various ship types are introduced, together with structural continuity and alignment in ship structures. With regard to construction materials, the book discusses steel, aluminum alloys and fiber reinforced composites. Various methods of steel material preparation are discussed, and plate cutting and forming of plates and sections are explained. The concept of line heating for plate bending is introduced.Welding power source characteristics, metal transfer mechanisms, welding parameters and their effects on the fusion zone, weld deposit, and weld bead profile are discussed in detail. Various fusion welding methods, MMAW, GMAW, SAW, Electroslag welding and Electrogas welding and single side welding are explained in detail. Friction stir welding as one of the key methods of solid state welding as applied to aluminum alloys is also addressed. The mechanisms of residual stress formation and distortion are explained in connection with stiffened panel fabrication, with an emphasis on weld induced buckling of thin panels. Further, the basic principles of distortion prevention, in-process distortion control and mitigation techniques like heat sinking, thermo-mechanical tensioning etc. are dealt with in detail. In its final section, the book describes in detail various types of weld defects that are likely to occur, together with their causes and remedial measures. The nondestructive testing methods that are most relevant to ship construction are explained. Lastly, a chapter on accuracy control based on statistical principles is included, addressing the need for a suitable mechanism to gauge the ranges of variations so that one can quantitatively target the end product accuracy.
