Weldolets are positioned on many mineral oil pipelines. The following questions had to be clarified: do the existing connecting pieces stand up to the varying stresses; which service life can be expected; and are there any additional measures or tests to be initiated for a safe operation of mineral oil pipelines.

At the Geesthacht Neutron Facility GeNF about 210 experiments were performed in 2003 by GKSS and by or for external users, partners or contractors. In most cases the measurements were performed and analysed in cooperation by the guest and by the GKSS staff or by the permanent external user group staff. The activities, which are based on a proposal ...
Specifications were investigated for high-energy Nd-YAG laser welding and atmospheric electron beam welding of Al and Mg alloys. The influence of the high welding speed of 10 m/min and more on the material structure, segregation and mechanical and technological characteristics of the welds was gone into. The investigations were carried out on comme...
