Abstract

Extensive laboratory tests have shown that needle peening the toe regions of fillet welds an cause a significant improvement in the fatigue performance of aluminum alloy fillet welds. This effect is most marked if peening is carried out after the application of any preload. Field trials carried out over periods of eight years on welded aluminum wagons operating on Queensland and New South Wales Railways, have confirmed the beneficial effects of peening. An alternative method of improving fatigue performance by TIG (GTA) dressing of weld toes has proved even more effective in laboratory tests. However, this technique has yet to be tested in field trials.
