Methodology for the Path Definition in Multi-Layer Gas Metal Arc Welding (GMAW)

The reconstruction of the geometry weld-deposited materials plays an important role in control torch path GMAW. This technique, which is classified as a direct energy deposition technology, experiencing new emergence due to its use welding and additive manufacturing. Usually, determined by computerised fabrication tools, but these software tools do not consider geometrical changes along case during process. aim this work adaptively define trajectories between layers analysing symmetry previously deposited layers. novelty integration profiling laser coupled production system, scans Once layer scanned, bead can be reconstructed continuous trajectory determined. A wall was fabricated under demanding conditions, surface quality around 100 microns mechanical properties line with those reported literature are observed.
