Cm - Identification drawingDf - At the Surface
Schematic drawing presenting the aspect of the cracking after Dye Check Test (Liquid Penetrant) in the external side of the line that operates at 800°C, insulated, and presented the leakage associated to the longitudinal seam weld of the fitting. The circumferential butt weld of the fitting to a pipe did not fail.

Cm - Identification drawingDf - At the Surface
Schematic drawing presenting the longitudinal section of the shell plate (sample removed from the boiler), at the position of the fillet weld (sealing weld) with a tube, where surface welding repairs created conditions for cracking the base material in a transgranular morphology. Several cracks were identify starting from the steam drum internal surface.
