Weld Root Erosion

Application

• Process & transport piping systems
• Chemical attack causing structural breakdown of sensitised area of weld adjacent parent metal
• Affected material eroded by product flow

Technique

• Conventional (zero degree compression wave) WT measurement techniques inappropriate because defects unfavourably position & orientated
• TOFD/R profiling offers most effective, comprehensive & efficient solution for detection & residual WT measurement

Result

Fast, efficient, reliable, repeatable, non-invasive, safe, high POD, non-comparative, residual wt value, immediate graphical results, hard copy evidence
