Cite as:

Thermal spray coatings are used in different fields of application. The combination of different coating materials with diverse thermal spraying processes enables the use of these technologies in a wide field of applications. ...  read more

The influence of beam positioning on the weld ability of dissimilar welding joints with high alloy TRIP/TWIP steels
Lars Halbauer, Anja Buchwalder, Rolf Zenker, Horst Biermann

Cite as:

In dissimilar welded joints without filler materials, the positioning of the electron beam is one of the most crucial factors in controlling weld quality. Among other factors, the small beam diameter and a highly accurate ...  read more
