THE PRESENT STATUS OF NONDESTRUCTIVE TEST METHODS FOR INSPECTION OF WELDED JOINTS IN SHIP STRUCTURES

The nondestructive test methods applicable to flaw detection in welds in ship structures are radiography, magnetic particle, ultrasonics, and fluid penetrants. At present, radiography is the most extensively used. The magnetic-particle method has found considerable application, and fluid penetrants are used occasionally, while the ultrasonic method has not yet been used on ship structures. Radiography, at present, is the most reliable and offers the best sensitivity to the detection of flaws in welds. The ultrasonic method offers a considerable potential and may prove more expedient than radiography if developed to provide the quality of inspection desired in welds in ship structures. The magnetic-particle method is established to the point where it serves as a useful inspection tool, particularly when used in conjunction with radiography. Further development may enhance its applicability. Filmless techniques such as xeroradiography and fluoroscopy offer some potential, but both require further research and development before they may be applicable to this type of inspection. The purpose of this report is to discuss the applicability of existing nondestructive test methods to the detection of flaws in welded joints in ship structures, and to make recommendations for further research, designed to improve these methods for the above purpose.
