Abstract:
This researh is studied of Non Destructive Testing application, AE method, to detect a low carbon steel corrosion.
This method detects an acoustic signal which this signal is occured form physical change of material, detected real time and capable
to detect before failure, which a revival is possible before a failure of the instrument. This research is studied a relation between
Corrosion Rate with the AE-parameter. The tested materials were low carbon steel grade A36 which use for storage tank construction,
were the base metal and weldment , the weldment preparation use shield metal arc welding for weld process. The solution condition is
Sulfuric acid, including, vary pH value between 4.5-6 with 0.5 step each, and activate the interaction in 24 hours, addition, control
the constant voltage at the optimize value(Ecorr). The results are recorded by set the AE sensor at the wall of the artificial tank. The results
find that corrosion condition and solution change as result of AE-parameter also changes, and the mathematic relation between corrosion
rate and AE-parameter are shown
