Laser induced arc dynamics destabilization in laser-arc hybrid welding [PDF]
Journal of Physics D: Applied Physics, 2019 The interaction between laser and arc plasma is a central issue in laser-arc hybrid welding. We report a new interaction phenomenon called laser destabilizing arc dynamics in kilowatt fiber laser-TIG hybrid welding of 316L stainless steel. We found the laser action significantly oscillates the arc tail with a 1~3 kHz high frequency.

Laser beam submerged arc hybrid welding: A novel hybrid welding process [PDF]
Journal of Laser Applications, 2018 The currently predominant joining process for constructional steel in the sheet thickness range of 40 mm, as is customary in pipeline and bridge construction, is submerged arc welding. Due to the large number of welding layers required, a high quantity of energy, expensive welding filler material, and also distortion are introduced into the component ...
