Rihui the ceramic backing of the weld bead

Supplied  By   RIHUI Ceramic Welding Backing

The NDT of Figures 15 and 16 demonstrate that the composition of the inclusions both in the root pass and the
final weld pass have the same constituents,despite having different proportions which indicates that there was no
contamination of the ceramic backing of the weld bead.
The NDT results(Figures 15 and 16)show that the elements found in the composition of the inclusion of the

root pass are not elements associated with the constitution of the cordierite,as this is composed of silica oxide,
magnesium and aluminium that are attributed to the oxidation of these chemical elements in the fusion well,
resulting from the addition of metal and base metal,particularly in the form of deoxidizers.
