Welding in the World, 2014
Hot-wire laser welding with a narrow gap groove was applied to ASTM A213 grade T91 steel in the application of ultra super critical boilers. A filler wire according to AWS A 5.28: ER90S-G was used. The effect of the depth-to-width ratio (D/W) of a weld shape on the susceptibility to solidification cracking was investigated. With a groove width of 3 mm,

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 ...

The Laser Welding with Hot Wire of 316LN Thick Plate Applied on ITER Correction Coil Case
Journal of Fusion Energy, 2014ITER correction coil (CC) cases have characteristics of small cross section, large dimensions, and complex structure. The cases are made of heavy thick (20 mm), high strength and high toughness austenitic stainless steel 316LN. The multi-pass laser welding with hot wire technology is used for the case closure welding, due to its low heat input and ...

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

High power and high brightness fiber lasers have been developed, and it is revealed that a deeper weld bead can be produced with an increase in the power density. Thus a 10 kW fiber laser with hot wire was used for butt welding of 590 MPa high-strength steel plates of 12 mm thickness with 0.4 mm gap. At the laser power of 10 kW and welding speed of 1 m/
