Management of railway infrastructure, as well as any other body that is reliable for monitoring the rail system, is responsible for building the most innovative infrastructure, which are usually financed by the Government as well as the burden of maintenance work throughout the railway system to be in the state suitable for use both conventional trains such as high speed as well as so-called “load” used primarily for maritime transport services. This can not be done unless the administration or agency concerned is not equipped with enough technological resources so that you can opt to certify and validate their suppliers and thus provide quality infrastructure needed for a sensitive and strategic sector such as railways.
The multiplication of the speeds of trains are operating at this time has resulted in significant multiplication of the dynamic stresses that all tracks and anchors must resist. Therefore, the purchase of any material, equipment or system must be subjected to stringent tests, carried out to verify that they are suitable and to confirm that they meet all the requirements that are required. In view of the fact that components are not standardized and vary widely from one provider to another, not only in form but also in composition (metals, polymers, ceramics and composites), it is essential to carry out independent tests on each one of them, and evidence as a whole in order to ensure that they respond adequately to all the elements interact. Today, the fact that the material supplied should be strong and tough is not enough, they are also obliged to give passengers more comfort FATIGUE TESTING OF WELDS OF MEETINGS FOR HIGH SPEED in railways A number of differences between normal welds and welds used in railway tracks: The composition, the types of stresses to which they are subjected, welding processes, etc.
