Pękanie spoin w procesie krzepnięcia

Abstract: Mechanisms of crystallizing fracture formation in the joints and in the heat-affected zones in the case of various of alloys were characterised, and feasible methods were given to keep them within limits. Pęknięcia krystalizacyjne w spoinieCharakterystyczną cechą pęknięć krystalizacyjnych jest ich usytuowanie wewnątrz spoiny najczęściej w osi (rys. 1). W procesie spawania krystalizujący metal spoiny znajduje się pod wpływem naprężeń rozciągających. Naprężenia te powstają w wyniku nieswobodnego skurczu spoiny i… Show more

“…Laboratory tests of homogeneous butt joints and dissimilar welded joints of T24 steel seemed to confirm the data of the steel manufacturer at first [25][26][27]. However, the research presented in the paper [27] showed a necessity of applying the initial preheating to the temperature of about 150…”

“…The main advantage expected of T24 steel apart from its high mechanical properties was the possibility of welding it without initial heating, and no necessity of conducting the postweld heat treatment with the thickness of a tube wall up to 10 mm [24][25][26][27].…”

“…6. Pęknięcie gorące spoiny, powstałe podczas spawania Wcześniejsze badania [10] wykazały, że w spoinie powstają pęknięcia międzykrystaliczne o gładkiej powierzchni przełomu. Ze względu na ich charakter i brak śladów odkształcenia można zaliczyć je do pęknięć gorących, wywoływanych przez dużą zawartość wodoru (rys.…”

“…The melted metal zone -white layer [1] has hard-to-etch structure of high hardness and brittleness [2]. In that zone (about 20 µm thick), changes of the chemical composition (as compared to the initial material) can be observed, as well as saturation of metal with gases (mainly nitrogen when cutting with the use of air plasma) [2,3]. In works [4,5], an effect of strong hardening of the layer situated near the surface of cutting performed with air plasma has been observed.…”
