Abstract
In offshore technology the quality of weldments is of great importance. In certain cases special electrodes are being used for underwater weldments whereas in different procedures a “habitat” is built around the weld joint in order to facilitate “dry” welding for a given water depth (pressure). Of course a number of weld material quality problems results from this.
With the purpose of optimizing the quality of such weldments different parameters like oxygen content, its distribution in the inclusions as well as the inclusion distribution itself have to be analyzed and correlated to mechanical properties. This is done with the help of SNMS, heat extraction and SEM systems.
