AWS (The American Welding Society) is the worldwide leader in certification programs for the welding industry. Since the CWI (Certified Welding Inspectors) program inception in 1976, AWS has certified more than 100,000 welding inspectors alone, plus thousands more working professionals across other certification categories. AWS conducts exams in locations around the world, including 550 U.S. sites and 40 countries each year. Many candidates mistakenly assume their field experience is enough to obtain certification, only to end up frustrated when they fail to pass their exam. Certification exams are intentionally comprehensive to ensure the welding industry the high-quality personnel needed to handle these complex roles. The process requires almost everyone to prepare to some extent – even those with years of experience:How much preparation? It depends upon your current skills and knowledge.Are the rewards worth it? The rewards are often worth the time you invest: certification can boost your earnings significantly and expand your career opportunities. While there are a few books that can be purchased from the AWS and outside sources on the CWI exam, there are no publications dedicated to helping CWI candidates pass the exam. This title was written for that express purpose. This work is a comprehensive collection of preparatory exam questions and answers for welders, inspectors, students, or anyone interested in the welding metallurgical field. The work boasts appendices that include tables, formulas, lists of organizations and major corporations employing welders and inspectors. David R. Quinonez has over 25 years of experience in welding, welding inspection, and nondestructive testing. He is currently a quality inspector performing dimensional, welding inspection, and nondestructive testing. His level II certifications include UT, MT, and PT. Past certifications also included level II RT, ET, ASNT level III MT, PT, and AWS-CWI. As a former civil service worker, Mr. Quinonez’s initial experience in nondestructive testing began while working on nuclear submarines and aircraft carriers. Subsequent positions included NDT and welding inspection on Rolls Royce gas turbine engines, F-22 stealth fighter airframes, missile defense, commercial/military rocket programs, pipeline, and structural steel on private sector and public works projects.

"Surviving, adapting, and thriving in a VUCA [volatile, uncertain, complex, and ambiguous] world"--Cover.
While it is mostly "behind the scenes," lubrication is used wherever you look—in all types of machines, vehicles, and aircrafts. Its usefulness is everywhere, in every industry, from all types of manufacturing, power, health, petrochemicals, food, paper, and metallurgy to small industries and agriculture. Lubrication is absolutely essential to the world. There is an undeniable link between maintenance strategy and lubrication reliability. Depending on the industry, maintenance costs can represent between 15-60% of the cost of goods produced. Therefore, the reliability of plant and equipment has a significant impact on the profits of any organization. Unfortunately, most problems related to machinery in plants are lubrication-related. To get maximum benefit from advanced maintenance strategies, an understanding of equipment lubrication is a must. That’s why this work is invaluable. Machinery Lubrication and Reliability contains everything a maintenance, plant, or industrial professional needs to know about lubrication theory, with vital information on all the critical equipment lubrication requirements. It illustrates how to improve reliability, maximize equipment life, eliminate unscheduled shut downs, and reduce operating costs. Rounding out this amazing package are questions and answers for those looking to obtain their ICML certifications. An affiliated web site (www.machinerylubricationreliability.com) contains additional questions for exam takers looking for extra practice. Features The only book that covers all the topics for the ICML certification course.Includes the industry standard API-614 throughout.Contains practice questions for the ICML exam at the end of each chapter, along with additional ones on the affiliated website.Dr. Trinath Sahoo is the General Manager of Indian Oil Corporation, Ltd, Paradip Refinery, in Odisha, India.

Written by a user for users, this unique book is designed for all managers who have been given the difficult task of bringing change to their organizations and making it stick. Drawing on his wealth of practical and proven experience, Thomas identifies and explains the eight key elements of changeleadership, work process, structure, group learning, technology, communications, inter-relationships, and rewards. He demonstrates that these elements are interrelated, and that they constitute a Web of Change. Thus, if one element is changed, its impact on the others must be understood and adjustments must be made to the entire system.

Divided into three basic sections, this unique resource provides a hands-on approach to implementing Lean manufacturing, pointing out the stumbling blocks and pitfalls to avoid. Its goal is to help American manufacturing more effectively go about the task of making Lean a viable process. The significance of the work is that, if followed, it could change the entire course of how Lean Manufacturing is implemented in the United States and help manufacturing, in general, to become more competitive on a world wide scale. The first section addresses the typical difficulties that manufacturing operations in the United States have with the implementation of Lean Manufacturing - pointing to three basic issues which if addressed and resolved, would serve to move the process forward in a much more rapid and effective manner. The second section focuses on how to fully resolve the issues noted and details four levels of Lean Implementation and how they can be measured, in terms of progress. The third section deals with the more advanced aspects of Lean Manufacturing, including such things as how to engage administrative and supporting functions in the process (Accounting, Materials, Sales and Marketing, etc.); how and why to perform a Core Process Analysis (in order to decide which processes should be considered for outsourcing); how to incorporate 'Owner-Operators' in the process; and, the importance of 18 month rolling implementation plan and more. It is sure to be found useful by manufacturing executives and managers at the factory level, as well as students in a Manufacturing and Industrial Engineering curriculum. This title provides readers with a clear path to inserting Lean in a manufacturing operation and a step by step approach to getting there. It includes numerous charts, graphs and window diagrams associated with the 'how to' - along with specific training and schedules. It offers some unique insight into where Toyota placed a very important focus verses what is typically understood and/or accepted as the general path of implementation it took. It contains a list of important 'Key Reflections' at the end of each chapter.
