Test specimen for preferential weld attack
Test specimen for preferential weld attack
(OP)
Hello all, I am seeking a metallurical lab / company in the Houston area who could assist me with the following.
I need to preferentially corrode a mock up A516-70 welded specimen in the weld zone to given depths. (Mechanical means not acceptable)The piece will be 0.75" thick and I would like to corrode areas of the weld to 10% 20% 30% 50% wall loss increments to qualify an advanced NDE Technique for a specific damage mechanism.
Suggestions greatly appreciated.

Alternatively you could make some mechanical grooves of different depths and then expose the whole weld zone to acid to get the rough-etched surface you may be looking for.
My company has its main metallurgical lab in Austin if you are interested.
