Title: Dietmar Schaftinger: Innovator in Laser Welding Technology

Introduction

Dietmar Schaftinger is a notable inventor based in Rheinberg, Germany. He has made significant contributions to the field of laser welding, particularly in the welding of hardenable steel. With a total of 2 patents to his name, Schaftinger's work is recognized for its innovative approaches to enhancing welding techniques.

Latest Patents

Schaftinger's latest patents focus on a method for laser welding one or more workpieces of hardenable steel in a butt joint. This method involves workpieces made from press hardenable steel, which must have a thickness of at least 1.8 mm and/or a jump in thickness of at least 0.4 mm at the butt joint. The process includes supplying filler wire into a molten bath generated by a laser beam. To ensure that the weld seam can reliably harden into a martensitic structure during hot forming, the filler wire contains at least one alloy element from a specific group, including manganese, chromium, molybdenum, silicon, and nickel. The mass proportion of this alloy element in the filler wire is larger by at least 0.1% by weight than that in the press hardenable steel of the workpieces.
