A control system for ultrasound devices utilized for inactivating E. coli in wastewater

Ohrdes, H.; Ille, I.; Twiefel, J.; Wallaschek, J.; Nogueira, R.; Rosenwinkel, K.-H. (Amsterdam [u.a.] : Elsevier Science, 2018)

Sonochemical processes applied to wastewater treatment have an influence on the behavior of ultrasonic systems. This is especially due to the load characteristic of the sonochemical process itself and the temperature ...
Influence of the ultrasonic vibration amplitude on the melt pool dynamics and the weld shape of laser beam welded EN AW-6082 utilizing a new excitation system for laser beam welding

Ohrdes, H.; Nothdurft, S.; Nowroth, C.; Grajczak, J.; Twiefel, J.; Hermsdorf, J.; Kaierle, S.; Wallaschek, J. (Berlin : Springer, 2021)

Laser beam welding is a commonly used technology for joining similar and dissimilar materials. In order to improve the mechanical properties of the weld, the introduction of ultrasonic vibration into the weld zone has been ...
Investigations on the effect of post treatment utilizing ultrasonic standing waves on the hardness of laser beam welds in stainless steel

Grajczak, J.; Nowroth, C.; Long, Y.; Twiefel, J.; Wallaschek, J.; Nothdurft, S.; Hermsdorf, J.; Kaierle, S. (Amsterdam [u.a.] : Elsevier, 2022)

Laser beam welding is precise, quick and highly automatable. Nevertheless, disadvantageous hardness profiles can result and promote cracking. By an ultrasonic post treatment, crystal defects, internal stress and grain ...
