subject: Important Things About Using Weld Testing [print this page] There are numerous metallurgical testing procedures which could determine the longevity and safety of welded components and structures. These procedures are essential when assessing the suitability of components for their intended use and making sure that relevant safety standards and industry specifications are adhered to.
Weld testing is the term for the one of the many destructive and non-destructive tests which assess performance and consistency and which are vital to guaranteeing the integrity and safety of the structure.
There are many methods for testing welds, such as tensile tests and other mechanical methods. One example is root bends - this is where you bend a portion of a weld between two blocks in a press to see if it cracks.
Specialist methods including radiographic, metallurgical and ultrasonic testing can also be used to evaluate welds. Whatever weld testing method is used, the end result provides vital knowledge on the standard of the welded component.
The same testing laboratory that provides your weld testing can also offer welding procedure tests, which can help you to ensure that all of your welding work is completed satisfactorily.
Welding procedure tests are completed in order to provide guidelines and instructions to the welder so that they may produce acceptable welds. There are various specifications put down for the welding of various materials, for example, there are different welding procedure specifications for each material alloy and welding type used.
These specifications define the conditions for the execution of welding procedure tests. The tests could be undertaken on the manufacturer's premises or at the research institution or testing laboratory.
Whatever industry you are involved in, from metal refinery to ship building, or chemical to petroleum, testing your component materials and ensuring welding is accomplished to the necessary specifications can save you time and money and allow you to provide a safe and high quality service to the end users.
