With the advent of disruptive additive manufacturing (AM), there is an increasing interest and demand high mechanical property aluminium parts built directly by these technologies. This has led to need for continuous improvement AM technologies processes obtain best properties in samples develop new alloys. study demonstrated that porosity can be reduced below 0.035% area Al-Mg manufactured CMT-based WAAM with commercial filler metal wires selecting correct shielding gas, gas flow rate,...
Additive manufacturing will be an option to develop prototypes or mechanical parts that made faster and cheaper than other techniques such as laser cladding electron beam. The main objective of this research was study the optimal initial conditions proposed additive system in order obtain metal prototypes. This have been presented taking into account measurements geometrical surface finishing. consist on integration a Fronius TPS 4000 CMT R welding machine with BF30 Vario Optimun CNC milling...
Cold metal transfer (CMT)-based wire and arc additive manufacturing (WAAM) of Ti-6Al-4V alloy has been investigated to manufacture walls with two different building strategies. This study focuses on the influence application thermal treatments resulting microstructure mechanical properties. Deep microstructural analysis revealed grades growth lamellae α phase after several at temperatures, which lead tensile properties better strength ductility balance compared as-built condition. Results...
This work analyzes the factors that affect manufacture of complex geometry parts by WAAM (Wire and arc additive manufacturing) with aim minimizing material used, improving Buy-to-Fly ratio (ratio raw weight divided final component) avoiding part distortions. A study different deposition strategies to (straight beads, circular path serpentine, overlapping beads...) has been carried out obtain desired geometry. Depending on strategy be used part, best option for definition robot trajectories...
