The position of the notch depth discontinuities in the material in general, we often use high frequency sound waves. However, in some cases with limited tools. The equipment used in the testing The Radiography by way of using the technique to locate the depth of a discontinuity that can be done as well. By using imaging techniques like trigonometry. The irradiated twice by radiation twice by moving the workpiece to a position where appropriate. Then measure the position of a discontinuity that move to calculate depth. The results of measurements of discrete tracks may be discrepancies result in reduced accuracy. As a result of the Contrast (contrast), sharpness (definition) or distortion (distortion) of the experiment is to build a replica of a defect. By means of a hollow punch. The size and shape different. The objective of this study was to compare the accuracy and the variables that affect the position of the notch depth discontinuities between Radiography, Digital Radiography and Film. By considering the different Screen Screen All Fuji Model ST-VI by means of digital photography. Film and Screen Brand Kodak Model AA400 for Radiography Film. The variables are the following. The impact of energy and visual filter to calculate the depth of a defect in the specimen. The X-ray test during power 120 140 160 180 200 220 240 kilovolts and the current 3.0 mA and a depth of 2 4 7 11 13 mm, material test sheet steel. Standard ASTM A36 by the specimen with a total thickness of 15 mm assembled with steel plates are 8 pieces in order to change the depth by moving the sheet metal sheets welded discontinuity to put in order the griddle. prepared to obtain the desired depth and the depth can be changed easily. Divided by the specimen's third appearance by piece, each piece is shaped and sized pieces of the specimen thickness of 2.0 mm, width 150 mm 250 mm 6 pieces and specimen thickness 1.0 mm wide, 150 mm, 250 mm, 1 piece by another. workpiece thickness 2.0 mm wide, 150 mm, 250 mm, 1 piece of a workpiece simulation creates a discontinuity in the workpiece simulation with a discontinuity that has divided kind of a defect cavitation in two. Nature is on the same specimen by simulating a deficiency of cavitation. Is a circle divided into four models varying in diameter, with a diameter 1 2 3 4 mm, respectively, and by simulating a defect cavitation is a rectangle divided into four formats, with the rest to be different. width 3 mm, length 10 mm footprint discrete angles 45˚ 90˚ 315˚ length and width of 3 mm to 6 mm 180˚ angle by switching the position of the sheet steel, which is generated. Roy is continuing to change the depth required by the Screen All Fuji Model ST-VI and scanned Screen Dynamix HR model for digital radiography. All film and Kodak Model AA400 for film radiography to store test results to be analyzed and image filters, 5 types of low pass filters. High Pass Filter High pass filter Advanced. Filter Line And the main filter Using the computer as a tool for analysis and digital processing. To translate the results to determine a digital file. By choosing the parameters of the test and the choice of photo filters. The test results from this research. After changing the parameter, then make the results of the experiment is to Radiography Film by Film Camera Brand Kodak Model AA400 which are calculated values, tolerances of less than shooting digitally. The Screen Screen All Fuji Model ST-VI and using image filters, including five species are filter high pass can not calculate deep because the invisible boundaries of discontinuation as a result of it. Filter else made the error in calculating the depth is changing the features of the filter itself in this research can be applied for use as alternatives to determine a value. Depth is another way Keywords: accuracy in determining the depth of a discontinuity is / Radiography Digital Radiography and film / visual filter.
