Welding Meaning,Characteristics and Design Industries

3.Welding Radiation Welding produces rays of longer wavelength compared to X-rays or gamma rays.These can be broken into visible- light rays,infrared rays and ultraviolet rays.Visible light rays emitted can cause eye strain and general discomfort.Ultraviolet rays are invisible and can cause burns on unprotected skin.Welding Inspection IndiaWeldsThe methods include visual,radiographic )X-rays,Gamma-rays),ultrasonic,magnetic,electrical (Eddy current methods),liquid penetrant,acoustic emission,thermography,optical holography etc.To read more about NDT and welding inspection techniques,here is a list of few useful pagesWelded Joint - an overview ScienceDirect TopicsThe internal weld is the strength weld and the outer is a seal weld.The joint can then be tested by pressurising the annular space between the two welds (usually with nitrogen at a pressure of 200 kPa),which permits pipe joints to be tested before backfilling the trench.On pipes smaller than DN 700 the weld should be made on the outside only.

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.Some results are removed in response to a notice of local law requirement.For more information,please see here.Radiography Testing - NDT Inspection - TWIIn 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.

Quality inspections - The FABRICATOR

To ensure quality welds,it is important to have a quality weld inspection program in place.In order to do so,a company must understand how to evaluate weld characteristics,determine weld quality,and have a welding inspector capable of performing a number of different testing methods.Physical Weld Testing Destructive Nondestructive - Weld Nov 27,2019 SUG II 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.Nondestructivie Weld Examination - lincolnelectricX-ray is used to determine internal soundness of the welds.The term X-ray quality, widely used to indicate high quality in welds,arises from this inspection method. Radiography is based on the ability of X-rays and gamma rays to pass through metal and other materials opaque to ordinary light,and produce photographic records of the
