Description of Work The work is divided into work packages (WP).
WP1
In WP1, the test pieces and the additives for LMD and DLF will be manufactured. The additives (powder and wire) will be characterised.
WP2
The aim of WP2 is the FE modelling of LMD and DLF processes to generate input for the process development (WP3). The main focuses are the calculation of the temperature and stress fields, as well as the microstructure formation in dependence of process parameters and part geometry.
WP3
In WP3, the process layout for LMD and DLF will be developed for different materials and part geometries. A further aspect in WP3 is the development of suitable heat treatment procedures after LMD and DLF processes.
WP4
In WP4, hard- and software for both techniques will be developed, modified and tested.
WP5
For quality assurance and reliable LMD and DLF, process monitoring and on-line process control systems will be developed and tested in WP5. The focus of this WP is the development of on-line process control methods.
WP6
Simultaneously with the process engineering in WP3, a geometrical and metallurgical examination of the test pieces will be carried out in WP6.
WP7
In WP 7, test pieces from different materials for mechanical testing are fabricated with the suitable parameters determined in WP3.
WP8
To ensure the required and defect-free structure of the processed parts, non-destructive tests (NDT) have to be carried out (WP8).
WP9
Based on WPs 2-8, demonstration parts will be repaired and manufactured in WP9 using the developed techniques and process chains. This work package includes the heat treatment, the final machining, NDT inspection and the mechanical tests.
WP10
In WP10, a technical and economical assessment of the results will be carried out. An additional essential aspect is working out the acceptance and NDT inspection criteria for LMD and DLF.
