Numerical simulation of wire temperature field for prediction of wire transfer stability in laser hot wire welding

ICALEO 2013: 32nd International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2013
With preheating wire by resistance heat, laser hot wire welding improves process stability and wire deposition efficiency, which gives broad potential applications in surfacing and narrow gap welding. It is a critical issue to control the temperature field of preheated wire in this process. Whether the temperature is so high that the wire fuses outside

Real-time monitoring of the laser hot-wire welding process

Optics & Laser Technology, 2014
Abstract The laser hot-wire welding process was investigated in this work. The dynamics of the molten pool during welding was visualized by using a high-speed charge-coupled device (CCD) camera assisted by a green laser as an illumination source. It was found that the molten pool is formed by the irradiation of the laser beam on the filler wire.

Development of a highly efficient hot-wire laser hybrid process for narrow-gap welding—welding phenomena and their adequate conditions

Welding in the World, 2013
The purpose of this work is to develop hot-wire laser welding for narrow-gap joints. Test pieces of ASTM A 304 stainless steel with a gap width of 3 mm were used. With welding by tentative filler rod made of Inconel 600 alloy, melting phenomena of the molten pool and the weld bead formation during welding were investigated by in situ observation using ...
