Paper Abstract
To research the formation and variation principle of the weld seam and molten pool for aluminum alloy high power fiber
laser welding, the welding experiments for 5052 aluminum alloy were carried out. The influences of laser power,
scanning velocity and protection gas on the welding process were systematically researched. The results show that with
the increase of power and scanning velocity, the depth to width ratio first increases and then decreases. The ratio reaches
the maximum value at 2.6 KW and 30 mm/s, respectively. When the power located at 2.6 KW to 2.8 KW or the velocity
located at 25 mm/s to 30 mm/s, stable deep penetration welding can be obtained. The weld seam shows relative flat
appearance and the molten pool presents typical “T shape” topography. Moreover, the protection gas also influences the
appearance of the weld seam. Using the independently designed fixture, the quality of the weld seam can be well
improved.
