Welding automation is one of the highly applied research that receives a lot of interest from scientists as well as application engineers in the industry. The welding task can be tedious for the workers; health affected by chemical smoke; or activity performed in a human restricted area. However, at present, manual teaching using Tech-pendant and off-line programming are still used in most industrial applications especially 3D complex curve welding. In order to improve the quality and quantity of the welding task, this research presents an effective automated method for extracting 3D curve seam welding using industrial robot. Firstly, by using a low cost 3D Camera and laser system which are attached at the end-effector of 6-DOF manipulator and combining with laser triangular image processing algorithm the position of path from start, mid, auxiliary, and end points coordinated of the welding line are recorded. Then by using interpolation algorithm the trajectory is calculated and transmitted to the 6DOF manipulator. As known that the angle of the weld head is also very important to the quality of the weld, so this research also proposes the method to adjust this angle during welding. Through implement experiments, the system proved that it is stable and have good precision. Installation time and maintaining are fast, not complicated and meet the automation demand.
