Abstract
Laser-arc hybrid welding has absorbed wide interesting in the past years due to its potential industrial applications, in which shielding gas plays an important role to achieve the effective laser-arc synergy effect and stable process. The effects of the shielding gas on the bead quality for laser-arc hybrid welding are reviewed. The mechanisms about the parameters of the shielding gas on process characteristics, bead shape and joint mechanical properties are discussed.
