  • DURIMPROVE: Improvement of welded structures fatigue life (durability) in high strength steels

    The fatigue properties of welded components can be improved by means of post-weld treatments, like TIG dressing or hammering. This article describes the results obtained in the research project “DURIMPROVE”, in which the effects of post-weld treatments on welds in high strength steel were investigated.

  • Electromagnetic pulse welding of similar and dissimilar materials - Weldability and mechanical properties

    The aim of the project is to generate all the necessary knowledge to develop a standard for this welding process, such as information on weldable materials, material combinations and dimensions, design of welded joints, recommendations regarding the minimum tests to be carried out, suitable welding parameters and welding windows, quality requirements and acceptance criteria, and this for a wide range of materials.

  • FATWELDHSS: Improving the fatigue life of high strength steel welded structures by post weld treatments and specific filler material

    This project developed techniques for improving the performance of welded, high-strength steels (yield strengths of 700 and 960 MPa) at thicknesses of 5-20 mm, for use in fatigue-loaded, welded structures, e.g., construction equipment, transportation vehicles and lifting devices. High frequency impact peening, weld toe laser dressing and low transformation temperature filler material were examined. Experimental and analytical procedures assessed the benefits and limitations of the selected methods. Full-scale testing demonstrated industrial viability and cost benefits. Practical implementation guidelines and design recommendations were disseminated.

  • FlowCurve: Optimising mechanical joining of multi-materials

    Selecting, simulating and optimising mechanical joining in a multi-material context set high requirements in relation to current material tests. Currently, no guidelines are available with regard to material characterisation for the support of the design of mechanical joining to achieve hybrid components. One of the objectives of this project is to standardise this. Which material tests must be performed for the characterisation of mechanical joining of dissimilar materials will be determined? An investigation will be performed within this context regarding how existing testing methods must be changed based on the new requirements.

  • Friction spot welding of aluminium alloys : Weldability and mechanical properties

    Investigation of new welding technology for aluminium

    The Belgian welding Institute has started a research project about a new spot weld technique; friction spot welding. The connection is created by using friction. This welding technology is particularly suitable for welding aluminium, and provides a solution to the difficulties that resistance spot welding is facing when joining aluminium, such as the electrode wear and tool life.

  • FRIEX : New friction welding method for automatic welding of pipelines

    The FRIEX project aims to develop a new variant of the friction welding process for fully automatic welding of pipes. Since pipe sections can have a length up to 18 meters, it is for practical reasons not possible to weld them using conventional friction welding. Therefore, a new variant of the friction welding process was developed. This research is conducted by the company Denys NV, and takes place in cooperation with the Belgian Welding Institute and laboratory Soete of the Ghent University and with support of the Flemish region (VLAIO/IWT).

  • HYBRISONIC: Ultrasonic supported processing of hybrid materials

    Metal-composite sandwich panels consist of two thin solid metal plates with in between a synthetic material (e.g. polyethylene), glued under high pressure. The metal plates, together with the plastic core, form a kind of sandwich plate. Different types of metals are used; mainly aluminium, but also stainless steel, coated steel, brass, titanium etc.

    The surface of aluminium sandwich plates is extremely flat, corrosion-free and has a low coefficient of expansion. The stiff aluminium sandwich plates combine these properties with excellent ink printing. This makes them ideally suited for stylish applications, such as advertising pillars, stand construction, advertising boards and displays.

  • INNOJOIN: Development and evaluation of advanced welding technologies for multi-material design with dissimilar sheet metals

    The INNOJOIN project provides insight in new modern welding technologies for welding of dissimilar sheet metals and helps companies to identify the most suitable welding technology for their products. During the project, a few representative cases were developed, based on the input of the participating companies.
