Hello Drew, he knew going in that he would be doing modifications to the hood, downpipe, etc. As to the die pen. etc., no we didn't do any of that. Fortunately, this was only going to be a temporary install as he had a completely new unit coming shortly. We also didn't want to invest a lot of time into this as it already had so many other cracks that had been addressed inadequately by the owner before the other student who did this work got to it. We did however, have a thorough discussion between the student who performed the work, the owner of it, and my partner and myself about what the causes likely were for it's initial failure, the effects of heat, the material type and how that could have contributed to the failure. The reasons why his initial repairs contributed more to additional problems than they solved and how when the part was originally built, they could have approached its fabrication differently and increased its life by doing so. For examples sake we could and probably should have done some die/pen checks to show possible inspection procedures. Thank you for the additional comments. Best regards, Allan
Allan,
This is for sure an intricate (sp) build. While I do not think that it is necessary to do PT on this part, it would for sure be a good one to learn off of, to look for false indications, tight spots requiring alternative means of cleaning to give true results, application of testing materials, ect. Lots of educational options for this. This does not even address the obvious dedication to the fabricator. Yes fabricator, even though a student.
This is a prime candidate for NDT training both before and after use. I would like to see it after 500 miles. :-)
