摘要

The influence of nickel-iron electrode properties and joint shapes on QT600-3 nodular iron joint strength and cracking was investigated using the Moire fringe method. The total displacement of these welded joints under uniax-ial tension was obtained. It was found that the newly developed nickel-iron electrode improved the welded joint strength. The experimental results also showed that double-V joint strength was higher than single-V joint strength, whereas single-U joint strength was lower than single-V joint strength. Single-U joint fracture was in the partially mixed zone of the weld root and parallel to the fusion line. This could be attributed to the complex compositions and structures at the weld root.
