Marking and micro-machining with nanosecond pulsed fiber lasers are maturing and elevating themselves from just simple marking lasers to far more capable micromachining tools.
Cover glass influence on high power fiber laser induced focus shift
Prevention of porosity by oxygen in partial penetration laser and laser-gma hybrid welding can stabilize the laser welding process and then prevent the weld defects.
Pulse Control improves the micromachining of hard materials demonstrates a factor of two improvements in cutting time and material removal if pulse peak power, energy and shape are controlled and optimized
Laser Beam Welding of Experimental Trip Steels
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
Single mode fiber lasers are sensitive to penetration spiking power modulation and beam rotation can minimize this effect
