Experimental Analysis of AA5083 Butt Joints Welded by CO2 Laser


Article Preview

Laser butt-welding of AA5083 has been investigated using a high quality CO2 laser in continuous wave regime. The effect of laser power, welding speed and specimen thickness on mechanical properties of the welded joints were evaluated by employing a general full factorial experimental plan design. The experimental results indicate important suggestion to choose proper combinations of process parameters and achieve high strength butt welded joints.
