چکیده مقاله
Increasing adoption of laser technology as an advanced thermal source is evident among various industries, notably in steel manufacturing In cold rolled steel production lines, laser welding plays a critical role in ensuring product quality and maintaining continuous processing The welding of thick steel sheets at high speeds within these lines necessitates the use of high power lasers operating in keyhole mode A 10 kW fiber laser welding system which is designed and manufactured in Iranian National Center for Laser Science and Technology operated in the pickling line of the Mobarakeh Steel Company's cold rolling mill the old CO2 laser was replaced by this system This paper reports the welding outcomes for a wide range of steel sheet thicknesses, from 2 mm to 5 3 mm, at optimized speeds between 4 5 and 9 m/min Substituting Helium with Argon as the shielding gas resulted in significant reduction of operational costs Weld quality was evaluated through multiple tests, including the Ericsson test, real time visual inspection of the weld seam, and metallographic analysis of weld cross sections The results confirm the robustness and stability of the high power fiber laser welding system and demonstrate its reliability of weld diverse grades steel sheets under industrial conditions
