Název v původním jazyce

Non-destructive real time monitoring of the laser welding process

Popis výsledku v původním jazyce

Laser welding is a high power density technology of materials joining that has many advantages in comparison with conventional fusion welding methods, for example, high accuracy, flexibility, repeatability and especially very narrow heat-affected zone which results in minimal workpiece distortions. Since it is still quite expensive technology, minimal spoilage is required. Effective system of quality control and processing parameters optimization must be established to reduce total costs, which is particularly required in industrial production. In this article some results of pulsed Nd:YAG laser welding process monitoring based on the measurement of plasma electron temperature are presented. The ability of designed sensor to detect weld penetration depth has been demonstrated. Plasma spectral lines intensities measurement can discover gap instabilities as well as local sheet thickness reduction.
