The influence of shielding gas in hybrid LASER–MIG welding
Applied Surface Science, 2007 Abstract Hybrid LASER-GMAW welding technique has been recently studied and developed in order to meet the needs of modern welding industries. The two sources involved in this process play, in fact, a complementary role: fast welding speed, deep bead penetration and high energy concentration can be achieved through the LASER beam, while gap ...

Comparison between hybrid laser-MIG welding and MIG welding for the invar36 alloy
Optics and Laser Technology, 2016Abstract The invar36 alloy is suitable to produce mold of composite materials structure because it has similar thermal expansion coefficient with composite materials. In the present paper, the MIG welding and laser-MIG hybrid welding methods are compared to get the more appropriate method to overcome the poor weldability of invar36 alloy.

Modeling the Transport Phenomena During Hybrid Laser-MIG Welding Process
Heat Transfer, Volume 3, 2003 Hybrid laser-MIG welding technology has several advantages over laser welding alone or MIG welding alone. These include the possibility of modifying weld bead shape including the elimination of undercut, the change of weld compositions, and the reduction of porosity formation in the weld. Although the hybrid laser-MIG welding method is becoming popular

CO2 Laser-MIG Hybrid Welding of Titanium Alloy
, 2009 In this study, CO2 laser – MIG hybrid welding process was investigated for butt welding of Ti-6Al-4V titanium alloy sheets, 3.0 mm thickness. The effect of hybrid welding parameters (laser power, arc pulse repetition rate, arc length, arc current, wire feed rate, relative positions of laser and MIG, welding speed) was investigated.
