Presented at ICALEO 2006
Innovative welding processes are continuously gaining industrial interest. Both hybrid laser welding (HLW) and friction stir welding (FSW) are automated welding processes which allow achieving high quality joints in aluminum alloys, in combination with a high productivity. It is important to assess the capability of the processes, not only in terms of weld quality but also in terms of productivity ...$28.00

Presented at ICALEO 2006
Laser hybrid welding combines laser and arc process to one process that has some advantages over both of the basic processes. The main advantage is the relief to the tolerances of laser welding. When this is combined with the advantages of laser welding, the hybrid welding process becomes an interesting solution for manufacturers of large products for improving their productivity. There have been many differe...$28.00

Hybrid welding is receiving considerable attention and is used in practical lines. And so YAG laser and MIG arc hybrid welding was performed on aluminum alloy to investigate the effects of various welding conditions on penetration and defect formation. In the case of YAG-MIG (laser-head-leading) hybrid welding, the surfaces of weld beads were by far prettier. The optimum distan...$28.00

Presented at ICALEO 2006
Laser joining of dissimilar materials is one of the core competence of BIAS and is of rising interest focussing new design concepts for weight savings in different fields in automotive and aeronautic industry. Beside the development of joining techniques for thin aluminum-steel sheets the joining of thicker material is of rising interest. Therefore specific processes have to be developed which allow dissimila...$28.00

Presented at ICALEO 2006
Laser GMA welding has demonstrated its fitness for industrial application in the past few years and is now widely regarded as an appropriate welding process for various applications e.g. in thick-section welding. However, as it is a combination of two welding processes, a wide variety of parameters has to be optimised. Moreover, due to the fact that the specific advantages of hybrid welding arise from the interaction of these two ...$28.00

Selective laser manufacturing (SLS/SLM) is applied for manufacturing 3D objects from different powders (Inox 904L, Ni625, Cu/Sn, W). Experiments were carried out on a PHENIX PM100 machine (50 W fibre laser, volume of fabrication: a 250mm diameter by 300mm height cylinder. Width of laser sintered line from Inox 904L powder on metallic substrate was studied applying different laser power P and beam velocity V (V=60-240mm/s) keeping effective energy input con...$28.00
