Title: Dieter Schneefeld: Innovator in Friction Welding Technology

Introduction

Dieter Schneefeld is a notable inventor based in Walkertshofen, Germany. He has made significant contributions to the field of friction welding, holding a total of 3 patents. His work focuses on innovative processes that enhance the efficiency and effectiveness of welding techniques in flow machines.

Latest Patents

Schneefeld's latest patents include a friction welding process and a shielding gas shower designed for executing this process. The first patent relates to a friction welding method for mounting blades of a blade carrier in a flow machine. This invention features multiple longitudinally extending welding surfaces on the blade carrier, which are oriented at a specific blade angle relative to the rotation axis. The welding temperature is achieved through the pressing together of the welding surfaces and simultaneous oscillating relative motion of the bodies in the welding plane. A shielding gas flows around the welding surfaces during this motion, creating a protective gas curtain.

The second patent also pertains to a friction welding process, specifically for mounting blades of a rotor in a flow machine. Similar to the first, it involves oblong welding surfaces on a carrier that are welded to the blade's welding surface. The welding temperature is generated by pressing the surfaces together and oscillating them relative to each other. Additionally, either the blade or the carrier is pre-heated to a temperature below the welding temperature at the welding surface.
