PREFERENTIAL CORROSION DATA -AIM

The aim of the project were twofold :To evaluate the effectiveness of a rapid test which could be used after fabrication. 2. To identify a weld which is susceptable and secondly to assess the capability of the scanning vibrating probe. 3.To provide information on the corrosion of welds. Tests were conducted on three welds produced by TWI UK, and designed to exhibit specific corrosion behaviour,and on a weld that had failed in service. The rapid test conducted was the galvanostatic test whilst long time immersion test were conducted to provide reference data.Measurement of the microhardness were made to establish the extent of linkage with the corrosion behaviour.
