EDITORIAL in the "Härtetechnische Mitteilungen" (HTM - Journal of Heat Treatment and Materials) by Rainer Braun

In his function as a board member of AWT e.V. and coordinator of the expert committees, Rainer Braun most recently presented the currently 18 active expert committees in the HTM editorial, issue 03/ 2018. The expert committees are the „innovation engine“ of the AWT, they initiate and accompany research and development projects in their field of activity, they offer member companies the opportunity to become part of the knowledge network through active cooperation, but above all to participate in the innovations.
In order to exchange knowledge between the expert committees, a workshop of all expert committee leaders is held annually in the presence of other members of the AWT board. Cohesion is thus strengthened, the requirements of technological change are taken up in a targeted manner and adopted in the technical committees.
