Hybrid Laser-GMAW Welding has benefits including;Higher travel speeds and deeper penetration than conventional GMAW, Lower heat input and less distortion than arc welding, Less filler metal usage for a given thickness and smaller melt volume than arc welding, Greater gap tolerance than autogenous laser welding, Alloying addition and joint filling that is not possible with autogenous laser welding and can be used in industries such as; Steel, Stainless, Aluminum, Copper, Nickel / Inconel, Titanium, Zirconium, Aerospace, Automotive, Defense, Energy, Heavy Manufacturing, Oil and Gas
On the Temperature Distributions and Thermal Stresses Induced in Laser Solid Freeform Fabrication of Multi-material Structures
In many different multidisciplinary engineering applications such as biomedical applications inconsistent material properties are required in order to enhance mechanical properties and functionality of an object. Laser Solid Freeform Fabricationas, an additive manufacturing technique can be used to manufacture fully functional near-net-shape three dimensional objects directly from their CAD model by successive layer-by-layer deposition of metallic materials.
Analysis of penetration depth fluctuations in single-mode fiber laser welds
Single mode fiber lasers are sensitive to penetration spiking power modulation and beam rotation can minimize this effect
Comparative analysis of GMA, laser, and laser-GMA hybrid welding
Comparative analysis of GMA, laser, and laser-GMA hybrid welding shows that laser and laser hybrid welding are very attractive for high and ultra high strength steels
