Development of High-efficiency / High-quality Hot-wire Laser Fillet Welding Process
Access this Article
The aim of this paper is to develop the high efficiency and high quality fillet welding technique using the combination of hot wire system and Laser welding. The melting of filler wire depends on wire current and there is an adequate vale of the current in each wire feeding speed. The leg length increases by the addition of filler wire compared with the non filler welding. The length is also larger than the laser irradiated area. This must be caused by the laser beam reflection on the molten pool surface. The results reveal that the parameter optimization leads to the stationary welding phenomenon. Besides, obtained welds have attractive properties, namely low heat input and low dilution.
