    Preliminary studies of seamless flux-cored wires stored in extreme conditions
    (2014) Fydrych, Dariusz Marek; Świerczyńska, Aleksandra; Landowski, Michał Karol
    In this paper, we describe the preliminary experimental studies of flux-cored wires moisturized under controlled conditions. Three seamless wires of different grades have been placed in an environmental chamber and moisturized in extremely adverse conditions (temperature T = 60°C, relative humidity H = 90%) for 240 hours. During this time, measurements of weight gain as well as surface observations of the wires have been carried out. Also, the amount of diffusible hydrogen in deposited metal was determined by the mercury method for one of the moisturized wires. A significant increase in the level of hydrogen was observed (from H5 to H10). Further research will aim to determine the effect of storage conditions on the hydrogenation of deposited metal and quality of flux-cored wires.
