Title: Oskar Kehrer: Innovator in Welding Technology

Introduction

Oskar Kehrer is a notable inventor based in Graz, Austria. He has made significant contributions to the field of welding technology, holding two patents that showcase his innovative approach to joining materials.

Latest Patents

One of his latest patents is for a shaft comprising a part connected thereto by welding. This invention involves a shaft with a co-rotating element secured to it, featuring a surface located perpendicular to the axis of the shaft. The welding occurs in the fillet formed between the seating surface of the shaft and the axially normal surface of the element. The design aims to achieve a durable join without adversely affecting true running, with a welding bead that starts at a specific point on the surface, leads to the fillet, and then returns to an endpoint on a surface transversely aligned with the shaft's axis. Another patent focuses on a method for joining a cast part and a case-hardened steel part. This method involves abrading surfaces on both parts to create a welding groove and utilizing high-energy beam welding with austenitic welding wire to join them effectively.
