Laser joining head assembly and laser joining method

摘要

There are provided a laser joining head assembly and a laser joining method for simultaneously performing joint tracking and seam inspection of a joint while said joining head assembly is in relative motion along the joint. The laser joining head assembly comprises integrated tracking laser line projecting means and integrated inspection laser line projecting means for respectively projecting a tracking laser line and an inspection laser line on the joint, thereby allowing to respectively generate successive joint transverse profiles and seam transverse profiles. These profiles are processed to respectively provide joint data and seam data, thereby allowing to perform said joint tracking and said seam inspection of said joint during said motion.
