• Fatigue Strength of the Welded Joints by Various Coated Electrodes

抄録

Although there are many data on the mechanical properties and toughness of weld metals of various kinds of coated electrode, only a few of reports will be found on the effect of types of coated electrode on the fatigue strength of welded joint, e.g. it is well known that the weld metal by low-hydrogen lime type electrode has better toughness than those by other type electrodes, but a low-hydrogen lime type electrode gives more rough and irregular bead form in comparison with other type electrodes. Therefore, it is not always clear, which type of electrode will give more beneficial welded joint in relation to its fatigue strength.<BR>This point was experimentally studied by this report. The obtained results are as follows:<BR>1) In the case of the same electrode, the fatigue strength of the vertical welded joint with reinforcement is 2-6 kg/mm² lower than that of the flat welded joint.<BR>2) The welded joint with reinforcement by low-hydrogen type electrode gives the higher fatigue strength of welded joint in comparison with other type electrodes.<BR>3) Titania type electrode gives the lowest fatigue strength of welded joint of all.
