Schweißen & Schneiden Flashback Part 2

Shaping the future with metallurgy

Filler metal specialist voestalpine Böhler Welding took advantage of the unique podium of Schweißen & Schneiden 2017 to showcase its achievements in the field of 3D printing with welding wires. Under the Böhler Welding brand name, itpresented an innovative range of specialized wire electrodes for 3D printing, developed from a basis of metallurgical expertise and application know-how in welding and cladding. 

Wire Arc Additive Manufacturing (WAAM), as this revolutionary technology is officially named, is rapidly gaining ground as a flexible and cost-efficient method for the on-demand creation of components from special alloys. It uses robotic gas metal arc welding to create any desired product shape by depositing the weld metal layer upon layer. The WAAM process can be automated completely from part design to fabrication in a CAD/CAM environment, reducing the production time and the amount of human intervention needed for each new part.

The challenge in WAAM is to produce complex-shaped metal components with a good geometric accuracy requiring minimal machining, in a variety of alloys and without loss of high-value material. This places high demands on the wire electrode in terms of consistent welding characteristics such as wire feeding, arc stability, wetting properties and control of spatter.  A new dimension in metallurgical expertise is the need to balance the chemical composition in such a way that WAAM produced components obtain the desired mechanical and chemical properties under welding conditions in a casting-like micro structure.   

The innovative Böhler Welding 3Dprint range consists of highest quality solid and cored wires with excellent surface finishing and the welding characteristics required for a stable 3D printing process. The available chemical compositions cover low- and medium alloyed steel, various types of stainless steel including duplex grades, nickel-base alloys, titanium and aluminium.
