THE FATIGUE STRENGTH OF FILLET WELDS. PART 2 - THE EFFECT OF FLUX TYPE

This report is part 2 of AWRA Report P2-226-78. The effect of electrode flux type on the fatigue strength of fillet welded load bearing cruciform joints is presented in the form of s/n curves for fillet welds having a similar minimum nominal tensile strength of 410mpa. The fatigue strength was studied over the range 10**5 to 2 x 10**6 cycles to failure using E4111, E4112, E4118 and E4127 electrodes and in addition a MIG/CO2 wire was also tested. There was a significant difference in fatigue strength among fillet welds deposited from these electrodes, particularly at 10**5 cycles to failure. Fillet welds from acid titania coated E4112 electrodes were significantly inferior over the whole range of cyclic lives, whereas fillet welds from the other electrodes tended to converge towards 10**6 cycles. The highest fatigue strength was exhibited by the slightly concave fillet welds deposited by the oxide coated E4127 electrodes and is attributed to a better stress flow through the concave fillet. The E4112 welds were characterized by slag inclusions having a linear morphology which is considered to be responsible for the poor fatigue performance of this type of weld metal (a).
