Abstract
A method and a system for laser beam welding two pieces abutted along a joint, wherein a camera configured to observe the joint is mounted integral with a welding head thereby defining a camera/welding head assembly. The camera/welding head assembly is moved along the joint and orthogonal positions of the joint are detected for positions of the camera/welding head assembly along the joint. A guiding mechanism guides a welding laser beam impact along the joint by controling an orthogonal translation of the camera/welding head assembly based on the orthogonal positions of the joint.
Claims21
A method for laser beam welding two pieces abutted along a joint, comprising the steps of:
- observing said joint with a camera, said camera being integral with a welding head thereby defining a camera/welding head assembly;
- moving said camera/welding head assembly along said joint;
- detecting orthogonal positions of said joint for positions of said camera/welding head assembly along the joint;
- observing a welding laser beam impact;
- and
- guiding said welding laser beam impact by controlling an orthogonal translation of the camera/welding head assembly based on said orthogonal positions of said joint.
A system for laser beam welding two pieces abutted along a joint, comprising:
- a welding head;
- a camera integral with said welding head thereby defining a camera/welding head assembly and configured to observe the joint;
- a movement mechanism configured to move said camera/welding head assembly along said joint;
- a detection mechanism configured to detect orthogonal positions of said joint for positions of said camera/welding head assembly along the joint;
- and
- a guiding mechanism configured to guide a welding laser beam impact along said joint,
- wherein said guiding mechanism comprises a control mechanism configured to control an orthogonal translation of the camera/welding head assembly based on said orthogonal positions of said joint.
