摘要：

The effect of weld size(L/T-p) on fatigue crack growth behaviour of Flux Gored Are Welded (FCAW) cruciform joints containing lack of penetration (LOP) defect has been analysed by using the strain energy density factor (SEDF) concept. Load carrying cruciform joints were fabricated from ASTM 517'F' Grade steel. Fatigue crack growth experiments were carried out in a vertical pulsator (SCHENCK 200kN capacity) with a frequency of 30Hz under constant amplitude loading(R=0). It was found that the crack growth rates were relatively lower in the larger welds fabricated by multipass welding technique than the smaller welds fabricated by the single pass welding technique.
