1. Towards Automation of Non-Destructive Testing of Welds
Sammanfattning : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

2. Non-destructive measurement of near-surface cracks in railheads : with focus on ultrasonic inspections
Sammanfattning : Near-surface cracks in railhead that caused by rolling contact fatigue (RCF) is one of a kind rail defects that degrade rail track quality. Dependent on the trail load, the cracks can reach to severe level quickly. LÄS MER
3. A human factors perspective on non-destructive testing (NDT) : detection and identification of cracks
Sammanfattning : .... LÄS MER
4. Development of a non-destructive field testing method for thermal assessment of district heating pipes
Sammanfattning : The thermal state of a district heating (DH) network governs the heat losses. It is a parameter considered if a change is to be made in the network. Heat losses are costly and economic aspects are important when planning for the maintenance or replacement of DH pipes. LÄS MER
5. In-situ assessment of density and material properties in timber structures by non-destructive and semi-destructive testing
Sammanfattning : ABSTRACTIn the assessment of timber structures, diagnostic investigations of the structural members and connections are generally necessary. The assessment often requires appropriate non-destructive testing (NDT) and semi-destructive testing (SDT) techniques. LÄS MER
