Radiographic Film Image Analysis of Austenitic Stainless Steel Plate Welding Seam
In order to determine the nature of the white strip on the film image in radiographic inspection of butt weld of the austenitic stainless steel plate,methods such as increase voltage of X-ray tube,change radiographic angle and cross-section liquid penetration test are adopted for analysis,it is proved that the indication is not defect but the diffraction stripe of the columnar crystal in the middle of the welding seam.
