Abstract

It provides precise information in real time on the support gas, the welding temperature and the distance, parallel to the welding plane, from the head to the join between the components. In addition to solving some of the technological problems encountered during laser welding, it provides a solution to the safety problem associated with applications in which it is used guided by optical fibre.
