Weld defect formation in rail thermite welds
A previously developed heat transfer model is used to study the influence of welding parameters on weld defect development in thermite welds. Weld defect formation maps are constructed from a series of heat transfer simulations. For the current normal rail thermite welding conditions, it is found that shrinkage cavity formation can be avoided but cold-lap and centre-line defects are likely to o...
متن کاملRelation between the geometry of rail welds and the dynamic wheel–rail response: numerical simulations for measured welds
The primary mechanisms playing a role in the dynamic wheel–rail response to rail weld irregularities in a ballasted track are pointed out. The concept of P1 and P2 forces for metallurgical rail welds, introduced in a first paper [1] concerning the present research, is further elaborated. The dynamic wheel–rail response is simulated for a number of geometrical rail weld measurements. Results sho...
متن کاملElectromagnetic Imaging Methods for Nondestructive Evaluation Applications
Electromagnetic nondestructive tests are important and widely used within the field of nondestructive evaluation (NDE). The recent advances in sensing technology, hardware and software development dedicated to imaging and image processing, and material sciences have greatly expanded the application fields, sophisticated the systems design and made the potential of electromagnetic NDE imaging se...
متن کاملNondestructive Testing and Evaluation of Steel Bridges
Nondestructive evaluation (NDE) is a means of evaluating structural components without damaging them. It can be used to evaluate structural systems, as well as specific structural components. Nondestructive testing is particularly useful for evaluating inservice bridges, since the bridges can remain in tact and open to traffic during the inspection and evaluation period. The NDE methods discuss...
متن کاملReview of Air-Coupled Transduction for nondestructive Testing and evaluation
Introduction Nondestructive testing (NDT) of structures and mechanical parts is increasingly receiving attention as the need to monitor the health of aging infrastructure and quality controls on the manufacturing of mechanical parts is becoming more apparent. NDT is defined as using various tools, whether they be acoustic, electromagnetic, or thermally based, to inspect the structural integrity...
