Checking 2.0 heads for cracks
A friend of mine works at a Non Destructive Inspection Lab, I asked him if he could check my 914 2.0 heads for cracks. Wow, what a process, he used a level 5 process, this is supposedly the highest level of dye penetrant inspection you can do. There are 7 stations to this process, initial dye dipping, rinsing, acid rinsing, controlled rinsing, developer dipping, drying then the actual black light inspection. The heads passed with flying colors...no cracks! Attached is a picture of one of the steps, this is the acid rinse.
