Abstract

This project addresses several design issues related to the strength of fillet welds and partial joint penetration (PJP) welds. The primary objective of this research are:

  1. Develop a rational explanation of the directional strength increase for fillet welds.
  2. Determine if length has a significant effect on the strength of fillet welds.
  3. Investigate the effect of loading angle on the strength of PJP welds.
  4. Investigate the fusion zone strength of PJP welds.
  5. Investigate the background of electrode strength coefficient, C1, in Manual Table 8-3. Determine the accuracy of C1 and propose new design values if necessary.

To meet the objectives of this research project, the available literature was reviewed, failure theories were used to derive theoretical equations, and experimental specimens with both fillet and PJP welds were tested.
