Abstract For welding of aluminium alloys with Harms and Wende medium frequency inverters (1000 Hz) we developed a special control mode AMC (Aluminium Mode Classic) and its extension AMF to handle aluminium alloys (mainly 5000th and 6000th alloys). These modes have been made to handle the alloy groups. The new methods cover every day issues as undefined oxide layers or other coatings. From the commercial side a standard inverter is used to reduce investments. Internal monitoring while welding is another important topic of this mode as well as constant weld time. The last item is the key topic for high volume production customers. Examples are shown for several surface conditions. Methods are suggested to preserve against crackles and cracks. In advance first tendencies in quality monitoring are presented using the force signal during the current phase of the welding process. In this paper we give the solution first before showing the background.
