Short Desciption:
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.
