Abstract

In the field of thermal spraying a lot of things have been and still are happening in education and training of personnel and in quality management. The QM-system that was established by the GTS e.V. - the association of thermal sprayers - was pioneer and does an excellent job concerning its requirements. The QM-requirements are completed by meanwhile created and internationally accepted EWF-education and training guidelines of supervising personnel and thermal spray workers. These guidelines involve also the new ISO standards of the thermal spraying co-ordinator and the approval testing of thermal sprayers. Meanwhile the ETS (European thermal sprayer) and the ETSS (European thermal spraying specialist) education and training courses are very much in demand. The EWF- thermal spraying specialist-education and training runs over a period of 3 weeks and fills therefor a gap in theoretical basic knowledge also of experienced co-workers. The EWF-thermal sprayer education and training ends in a theoretical testing and also a practical testing according ISO 14918 (approval testing of thermal sprayers). Here, different destructive testing procedures are required depending on the spray process, which provide useful statements concerning the quality of sprayed coatings. The ISO ½ of the 14922 series follow also the main aim to spray reproducible coatings. They may be combined very well with the GTS guidelines, because the latter contain mostly all the requirements of the ISO standard and there exists an obligation of adoption into the GTS guidelines. The ISO personnel qualifying and quality management standards result together with the EWF education and training guidelines in a sound QM-system, which meets the increased demands of trade and industy of high quality sprayed coating.
