Control of the tightness of welded joints by the bubble method

Modern welded structures are characterized by a wide variety of forms, areas of application and structural solutions. You can mention, for example, pipelines, tanks, silos or ventilation pipes. Most of them are non -pressure structures and their admission to operation is possible, including due to the tightness of welded joints. Tested by the bubble method, which is not only highly efficient, but also economical. The short characteristic of the bubble method
The bubble method is used to verify tightness by immersing the analyzed object into a control liquid or by covering the surface of the object with a solution of a surface-active substance, i.e., foaming substance. The control of welded joints is carried out in atmospheric air during a vacuum created by a liquid indicator supplied to the controlled section of the weld. This method uses the phenomenon of gas penetration from an environment with higher pressure in Wednesday with lower pressure, provided that the appropriate connection is available. Such a combination of media of different pressure is capillary leaks located in the junction. This pressure difference causes the appearance of a clearly visible bubble at the site of the defect. The bubble method is fast and easy to use. It allows you to detect even very small leaks without spending money on ultrasonic tests that are much more expensive. Where is the bubble method used?
The aforementioned method of testing tightness is used in steel structures, the purpose of which is associated with the transportation or storage of liquids or gases. These are all kinds of tanks and pipelines, compliance with the complete tightness of which is of great importance for the safety of the object and its users. The tightness of welded joints can be checked in certified laboratories specializing in non -destructive control. Such units should be characterized by modern equipment and an experimental team of specialists. Conducting non -destructive tests gives the manufacturer a guarantee that the products he manufactured complies with all quality standards. Identification of defects at the initial stage of production reduces the costs associated with the possible repair of defective elements. It is worth adding that non -destructive control is also used to evaluate steel structures in operation.
