WAAM and Conventional Joining

A Brief Introduction

This research discipline includes projects in two sub-disciplines; Wire Arc Additive Manufacturing (WAAM) and conventional joining methods. WAAM employs an arc as a heat source to create a molten pool into which a continuously fed metal wire is deposited. This additive manufacturing technique is ideal for rapid prototyping or repairing large-scale metal components. On the other hand, conventional joining involves other welding methods and brazing. Both methods leverage a heat source, but WAAM builds up structures additively, while conventional joining fuses distinct components.

Projects

In our brazing project, we utilized copper as filler metal for stainless-steel plates, chosen based on its optimal melting temperature. Through meticulous testing, we identified the suitable 30-micrometer thickness for consistent results. Our innovative brazing process, tailored for heating, holding, and cooling stages in a vacuum, ensures precise bonding without melting the base plates. Addressing challenges in material selection, filler metal thickness, and heat cycle optimization, our research advances efficient and reliable brazing practices for ...
