Radiography Testing - NDT Inspection - TWI

In Radiography Testing the test-part is placed between the radiation source and film (or detector).The material density and thickness differences of the test-part will attenuate (i.e.reduce) the penetrating radiation through interaction processes involving scattering and/or absorption.Radiographic evaluation of gas tungsten arc welded joints Mar 01,2019 austenitic stainless steel storage tanks butt welds Gamma rays test#0183;Fig.2(a) shows photograph of examined expansion tank with three butt weld joints (W1,W2 and W3) made by GTAW using TIG weld arc SS 316 L filler metal with diameter of 2.5 mm.The welding was performed with current 120 A,speed 1.7 cm/min,argon gas flow rate (shielding gas) 8 lit/min and nozzle to plate distance 3 mm.Butt joint W1 is made by Radiographic evaluation of gas tungsten arc welded joints Mar 01,2019 austenitic stainless steel storage tanks butt welds Gamma rays test#0183;Fig.2(a) shows photograph of examined expansion tank with three butt weld joints (W1,W2 and W3) made by GTAW using TIG weld arc SS 316 L filler metal with diameter of 2.5 mm.The welding was performed with current 120 A,speed 1.7 cm/min,argon gas flow rate (shielding gas) 8 lit/min and nozzle to plate distance 3 mm.Butt joint W1 is made by

Radiographic and Ultrasonic Testing of Welds

Radiographic Testing (RT) This method of weld testing makes use of X-rays,produced by an X-ray tube,or gamma rays,produced by a radioactive isotope.The basic principle of radiographic inspection of welds is the same as that for medical radiography.Radiograph Interpretation - WeldsExcess weld reinforcement is an area of a weld that has weld metal added in excess of that specified by engineering drawings and codes.The appearance on a radiograph is a localized,lighter area in the weld.A visual inspection will easily determine if the weld reinforcement is in excess of that specified by the engineering requirements.Physical Weld Testing Destructive Nondestructive - Weld Dec 12,2019 austenitic stainless steel storage tanks butt welds Gamma rays test#0183;The back bend test is a type of physical weld testing that is used to determine the quality of the weld metal and the degree of penetration into the root of the Y of the welded butt joint.The specimens used are similar to those required for the free bend test except they are bent with the root of the weld on the tension side,or outside.
