Flash x-ray diagnostics of high speed dynamic tests need to be reliable as the test may be quite expensive and time consuming. Preparation for a first time test can involve many partial or preliminary tests to verify adequacy of x-ray energy, x-ray exposure, film/screen combination, film holder protection, flash x-ray generator protection, triggering and timing techniques. Once these preparations have been successfully completed, very informative results are attainable for a variety of tests including jetting, welding and casting.
