Abstract
The present invention relates to a kind of method that lead chi confirms egative film position, comprise before being characterized as ray detection, part entirety is observed, a datum mark is set in non-detection region, as the starting point placing lead chi, can place one or two lead chi as required on two dimensional surface, lead chi must be non-detection region in the position of egative film；Carry out radiography detection, can go out, according to the position resolution of lead chi in egative film, the part position irradiated.
Description
Technical field
The invention belongs to part technical field of nondestructive testing, relate to a kind of method that lead chi confirms egative film position.
Background technology
For large scale and baroque part, during detection, need the concrete shape according to part and test section
Position is cut into different size egative film, and a part is accomplished by up to a hundred egative films, for ease of distinguishing, at electrophotographic process
In, need to put code of monitored location, in order to make egative film and tested position one_to_one corresponding, it is simple to search every time.This side
The shortcoming of method is: need each position to place mark, loaded down with trivial details and lose time, and easily exists certain artificial
Error.
Summary of the invention
The technical problem to be solved in the present invention: a kind of method providing lead chi to confirm egative film position, can solve
The problem distinguishing egative film correspondence part position, improves detection efficiency, improves accuracy.
Technical scheme:
A kind of lead chi confirms the method for egative film position, comprises the steps:
The first step, sets datum mark, before ray detection, observes part entirety, sets one in non-detection region
Datum mark, as the starting point of placement lead chi, the detection arranging beneficially part of this datum mark；
Second step, prepares a special lead chi, and scale above is font, can demonstrate on egative film；
3rd step, arranges lead chi in non-detection region, before part transillumination, and can be as required on two dimensional surface
Placing one or two lead chi, lead chi must be non-detection region in the position of egative film；
4th step, radiography detects, carries out radiography detection, go out photograph according to the position resolution of lead chi in egative film
The part position penetrated.
Beneficial effects of the present invention: lead chi of the present invention confirms the method for egative film position, is positioned by lead chi, decreases
Put the work of code of monitored location, shorten transillumination and arrange the time.
Detailed description of the invention
Below in conjunction with specific embodiment, the step of the present invention is described in detail.
The present embodiment selects main blade, it is carried out the location of the lead chi before ray detection, comprises the following steps:
The first step, sets datum mark, before ray detection, observes main blade entirety, owing to whole main blade all needs
Ray detection to be carried out, its length is about about 6 meters, so the either end of main blade is set as datum mark,
As the starting point placing lead chi.
Second step, prepares a special lead chi, and scale above is font, can demonstrate on egative film；
3rd step, arranges lead chi from one end of main blade to the other end, runs through the whole length of part, actually detected
Middle according to exposure parameter difference, main blade is divided into different detection regions, these regions along radially dividing,
Consistent with the arranged direction of lead chi, such lead chi just can translate, and meeting lead chi in the position of egative film is non-detection zone
The requirement in territory；
4th step, carries out radiography detection by region to main blade, goes out photograph according to the position resolution of lead chi in egative film
The part position penetrated.Such as the position at 950mm, for the initiating terminal of coating iron at the leading edge, in the position of 6000mm for joining
Weight box.The relevant position of main blade can be quickly found by lead chi.
Claims (1)
