Bugger. Good that it's a short list, but painful none the less.
It's interesting how every engineer interprets the rules differently. NCOP makes mandatory requirements for welding on suspension and steering components. I guess your engineer felt the crossmember was a suspension component. It could be worse... the Mandatory requirements for those are a report including:
- material specifications of the component to be modified;
- a specification of weld material and compatibility with the parent material if welding is
involved;
- description and/or diagrams of the preparation of the component if welding is involved;
- details of weld procedure used including method of weld procedure qualification if
welding is involved;
- details of welder qualifications and method of qualification if welding is involved;
- details of preheating used if required prior to the modification;
- details of heat treatment procedure after modification;
- hardness testing before and after modification of the modified zone; and
- results of non destructive testing.
Glad he didn't ask you for all that.
For the testing, the home kit he is referring to is probably dye penetrant. Clean everything up immaculate (no paint), spray on the detector, then spray on the developer. The developer gets stuck in any cracks. The workshop version is probably mag particle. It can be done through paint, though is more accurate if the paint is off. You magnetise the part, put particles on it and see how they "line up" around hidden defects.
The mag wheel bit is fairly picky. He is correct... NCOP requires alloy wheels to be compliant to either Wheel Industries Association (Australia) (WIA), Standards Association of Australia (SAA), TÜV or JIS. The frustrating bit is that so very, very few wheels comply (I would wager a carton of beer that none of Clay's stash of 60's, 70's and 80's rims is compliant).
Good luck with the rectification works.
