Information × Registration Number 0216U003811, 0113U003491 , R & D reports Title Develop technology for pressure welding and technical design for a machine for welding pipes for repair of railway wagons. popup.stage_title Head Kachinskiy V.S., Registration Date 18-02-2016 Organization E.O.Paton Electric Welding Institute of National Academy of Sciences of Ukraine popup.description2 The optimum value of the components of the magnetic field for pipes of small diameter to 60 mm. Axial component of the magnetic field affects the position of the arc in the gap between the ends of the pipe welding that determines the quality of welded joints. The main technological options for repair work on welding the pipes in stationary and field conditions are: the quality of the ends of pipes; size and distribution of induction magnetic field; voltage arc; size and order of welding current programming; closing speed arc gap in the implementation of sediments. A study to determine the impact of liquid molten metal in the arc gap during heating in the formation of welded joints of pipes. Shifting arc on the outer edge of the tube is accompanied by an abrupt increase in arc voltage and increase its speed. The quality of welded joints of pipes depends on the position of the arc at the ends of pipes. Metallographic studies showed no pores through the weld. Measurement of hardness through the base metal -HAZ- line connection -HAZ- base metal showed increasing hardness of 10 ... 15% through the weld. Experimentally, the influence of liquid molten metal in the arc gap during heating in the formation of welded joints of pipes. Develop existing technology for press welding in the repair Railroad wagons and greenhouses. A study to determine the influence of the main process parameters during heating and draft ends when connecting pipes of air in terms of car-repair businesses and greenhouse plants magnetically pressing welding arc.
