 pdf fileWelding Fabrication Standards
In this framework The Italian institute of welding (Istituto Italiano della Saldatura - IIS), has developed• the following educational tools for the classroom instruction: − slide presentation through computer projector, to be used by teachers during the training courses; − books (electronic and/or paper format), to be used by participants; − exercise questions, to be used during classroom instruction. This book is therefore meant to provide direct and clear information on European standards relevant to welding fabrication, as these are subject to continuous updating; therefore knowledge of requirements of the standards is to be considered basic knowledge for welding co-ordinators and inspection personnel. Moreover this book has been recently integrated taking into consideration guidelines produced by EWF for the application of ISO 3834 requirements, produced after several years of experience of its members in technical assistance on the field of welding fabrication, education and training of welding and NDT personnel and in certification of welded products manufacturers.

 pdf fileWelding and Related Processes for Repair and Maintenance Onboard
rnINTRODUCTIONrnA ship at sea depends upon the knowledge, skills and self-reliance of the crew to carryrnout necessary maintenance and repair work. One of the important skills required is arngood command of modern welding techniques.rnThe purpose of the Welding Handbook for maritime welders is to provide guidancernin modern welding and related processes and to provide the welder with a source ofrnpractical information on the right solution to specific onboard welding problems.rnExperience gained from user contact and welding training of crewmembers showed thatrndocumentation aimed specifically at on board welding solutions was needed. This ledrnto the development of the first welding handbook for on-board repair and maintenancernwelding already the 1950es.rnThis edition of the Welding Handbook builds upon all the earlier editions and onrnWilhelmsen Ships Service’s business activity
