  1. 1. Towards Automation of Non-Destructive Testing of Welds

    Author : Patrik Broberg; Mikael Sjödahl; Anna Runnemalm; Torbjörn Löfqvist; Högskolan Väst; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Welding; non-destructive testing; NDT; Industriell arbetsvetenskap; Industrial engineering; Experimentell mekanik; Experimental Mechanics;

    Abstract : 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.

  3. 3. In-situ assessment of density and material properties in timber structures by non-destructive and semi-destructive testing

    Author : Thomas Kruglowa; Chalmers University of Technology; []
    Keywords : X-ray; Vasa warship.; semi-destructive testing SDT ; density determination; non-destructive testing NDT ; calibration procedure; Keywords: In-situ assessment;

    Abstract : 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. READ MORE

  4. 4. Surface Wave Testing of Pavements

    Author : Nils Rydén; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Hydrogeology; inversion; guided waves; road; pavement; Surface waves; non-destructive testing;

    Abstract : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. READ MORE

  5. 5. Non destructive testing methods for integrity determination of concrete structures

    Author : Jon Rasmussen; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : The ageing of concrete structures can be a threat to human safety as well as being a huge economical factor in the near future. Lifetime prediction and damage assessment of concrete structures will be a growing part of infrastructure planning. READ MORE
