Wire and Arc Additive Manufacturing (abbreviated: WAAM) is a method to produce metal parts by adding and depositing material layer by layer. This technique uses a (standard) welding robot with a welding wire (electrode wire). These welding robots can deposit several kilos of material per hour, which enables the production of larger parts (up to approximately 2 x 2 m) in a more cost efficient manner and faster than with other additive manufacturing techniques (usually based on powder).

Additive Manufacturing (AM) has brought a lot of progress in the recent decades for a wide range of applications within the industry, biomedical sector and consumer market. The main advantages of this technology are the great freedom of form with minimal use of material.

BWI and VIVES have started a research project on the weldability of additively manufactured and conventional components.
The following themes will be investigated:
- Which processes can be used to connect metal-printed parts to conventionally manufactured pieces?
- Guidelines for the optimal combination of conventional techniques and AM techniques.
- What are the consequences of the applied welding process for the (mechanical) properties of the parts and for the connection itself?
