Microstructural characterization and tensile behavior of Nd:YAG laser beam welded thin high strength low alloy steel sheets
TL;DR: In this article, the Nd:YAG laser source was used to join high strength low alloy (HSLA) steels compared with conventional fusion welding processes, and the microstructure evolution of the fusion zone was recorded through optical, scanning and transmission electron microscopy.
Journal ArticleDOI
A microstructural and low-cycle fatigue investigation of weld-repaired heat-resistant cast steels
TL;DR: In this paper, a multi-pass weld repair of heat-resistant cast steels is carried out using an automated shielded metal arc welding (SMAW) process, with various filler materials and pre-heating at 400°C.

A new fracture mechanics method to predict the fatigue life of welded cruciform joints
TL;DR: In this paper, the fatigue life of MIG welded cruciform joint failing from root (LOP) region was successfully predicted using new fracture mechanics equations, which were developed by combining Paris' law and ΔK i -endurance equation and incorporating an integral factor ( I p ) obtained by integrating Paris' equation.

Fatigue behaviour of laser welds of high-strength low-alloy steels
J. Oñoro,C. Ranninger +1 more
TL;DR: In this paper, the performance of laser-welded high-strength low-alloy (HSLA) steels has been evaluated under the present test conditions of 260 MPa and showed that cracks usually start in the fusion zone, near to the borderline between the fusion and heat-affected zones, the cracks growing right into the base metal by the transcrystalline cracking process.

The effect of a long post weld heat treatment on the integrity of a welded joint in a pressure vessel steel
TL;DR: In this article, the effect of post weld heat treatment on microstructure and mechanical properties of a welded joint in a 0·2%C-1·4%Mn-0·5%Mo pressure vessel steel was studied.
Journal ArticleDOI
Experimental investigation of fatigue behaviour for welded joint with mechanical heterogeneity
TL;DR: In this paper, the effect of mechanical heterogeneity in welded joints on the fatigue damage behaviour and fatigue crack initiation life was also investigated, and the results indicated that the fatigue behaviour is markedly different in three zones of welded joint; there is a trend toward reduction in the fatigue life of HAZ as compared with the base metal.
