Possibilities for Qualification and Certification of Personnel,Companies and QM-Systems in the Field of Thermal Spraying

摘要

In the thermal spraying technology a lot of things have beenand still are happening in education and training of personneland in quality management. The QM-system that wasestablished by the GTS e.V.– the Association of ThermalSprayers – was pioneer and does an excellent job concerningits requirements. These GTS QM-requirements are meanwhilecompleted by newly created and internationally acceptedEWF-education and training guidelines of supervisingpersonnel and thermal spray workers. These guidelinesinvolve also the new ISO standards of the Thermal SprayingCoordinator and the Approval Testing of Thermal Sprayers.Meanwhile the ETS (European Thermal Sprayer) and theETSS (European Thermal Spraying Specialist) education andtraining courses are very much in demand. For the QMSystemthe standard ISO 14922 Part 2-4 (Quality requirementsof thermally sprayed structures) is established, which includesthe standard ISO 14918 (Approval Testing of ThermalSprayers). Here, different destructive testing procedures arerequired depending on the spray process, which provide usefulstatements concerning the quality of sprayed coatings. Withthe GTS-Certification, the EWF-Qualifications and the ISOStandards a System is installed, which meets the increasedDemands of Trade and Industry for High Quality SprayedCoatings.
