  1. 1. An inductive gap measurement method for square butt joints

    Author : Edvard Svenman; Anna-Karin Christiansson; Anna Runnemalm; Johan Carlsson; Högskolan Väst; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy current; Seam tracking; Measurement; Laser beam welding; gap geometry; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. READ MORE

  2. 2. Sound and vibrations in structures with air enclosures

    Author : Anna Runnemalm; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Vibrations in thin shell structures and sound fields in enclosures are investigated as well as the interaction between such structures and the enclosed sound field. Optical, non-contacting methods as TV holography, shearography and laser scanning vibrometry are used to investigate vibrations of thin shell structures with air enclosures. READ MORE

  4. 4. 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.

  5. 5. Combined Digital Holography and Speckle Correlation for Rapid Shape Evaluation

    Author : Davood Khodadad; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Maskinteknik; Mechanical Engineering; Experimental Mechanics; Experimentell mekanik;

    Abstract : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing thecontrolled parts. READ MORE
