Radiographic testing of magnetic, non-magnetic, numerical, letter, symbol, lead type
1、 Use of radiographic testing lead type:
In radiographic testing of welds, castings, and other materials, different combinations of Arabic numerals, English letters, and Chinese characters are commonly used as identification marks (such as workpiece numbers, weld codes, and radiographic dates). The use of lead numbers can vividly and intuitively express the marking requirements of the film.
2、 Radiographic inspection lead specifications:
Lead type, lead code, flaw detection, lead type, radiographic testing, lead type
Medium lead: Number marking for X-ray inspection, size: 7 * 4 * 1, 100 pieces/bag
Magnetic lead type: X-ray inspection film plus size mark, size: 7 * 4 * 1, 100 pieces/bag
Large lead type: X-ray inspection film large number mark, size: 13 * 9 * 2, 100 pieces/bag
Extra large lead type: X-ray inspection film with 100 large number markings per bag
3、 Radiographic testing lead type model:
Arabic characters: 0-9
English: A-Z
Chinese characters: Year Month Day Up Down Left Right
Special symbols: center mark, overlapping mark arrows R1 R2 R3, can be customized if there are other special requirements.
4、 Disadvantages of commonly used identification codes in radiographic testing:
Low work efficiency. In radiographic testing, digital offset is used as a film identification mark, and nearly a hundred lead letters (10 for each number, which is 100) need to be prepared every time they go to the site It is quite time-consuming to find the required numbers among hundreds of lead letters, although we have taken some measures such as sticking the lead letters on adhesive tape. However, due to the adhesion of the tape, it is also time-consuming to reattach the lead letters after use Sometimes, due to the inability to find the required lead type for a long time, other lead types have to be shaped and replaced, resulting in non-standard numbering and posing certain difficulties for film evaluation.
