Summary: By introducing the low current pulsed gas metal arc (GMA), the bridging ability of laser beam welding (LBW) can be improved. This paper establishes three-dimensional transient mass and heat transfer models to investigate the impact of the additive GMA on LBW. Comparative analysis of temperature and flow fields in the molten pool shows that the additive low current pulsed GMA significantly increases the high temperature region and expands the molten pool, improving the bridging ability of LBW.

Summary: A split anode calorimeter (SAC) was developed to measure the energy density of plasma transferred arc (PTA). The SAC was calibrated using a laser beam with a well-defined energy profile. The results confirmed the accuracy of the SAC method and its suitability for measuring the energy distribution of an electric arc. It was observed that the PTA energy profile was distorted when crossing over the split anode interface of the SAC, but this was corrected by adjusting the position of the ground wire. Analysis of the energy density profiles generated from current density and temperature distribution showed that the effective energy distribution is wider than the width of the arc column due to other energy transfer processes.

Summary: In this study, the microstructure of the titanium alloy Ti-6Al-2Sn-4Zr-2Mo-0.1Si (Ti6242) was compared to the commonly used alloy Ti-6Al-4V (Ti64) when deposited using a wire-arc additive manufacturing (WAAM) process. The application of inter-pass machine hammer peening successfully refined the grain structure of Ti6242, producing a finer equiaxed grain structure with a near-random alpha texture. This refinement was attributed to the presence of molybdenum in Ti6242, which led to slower grain growth during reheating and a finer transformation microstructure.

Summary: A functionally graded AlxCoCrFeNi high entropy alloy with a variation in Al concentration along the building direction was successfully produced using a hybrid powder-bed wire-based direct energy deposition process. The alloy exhibited a continuous transition from a single FCC structure to a major BCC+minor FCC dual-phase structure, which was facilitated by the remelting and reheating process during the deposition. The mechanical properties of the alloy showed higher strength and hardening rate but lower plasticity in areas with higher Al content.

Summary: In this study, the fatigue strengthening of damaged steel members was conducted using a directed energy deposition (DED) process called wire arc additive manufacturing (WAAM). Experimental and finite element (FE) simulation results showed that the WAAM process introduced compressive residual stresses at the crack tip and stress concentration at the root of the as-deposited WAAM, which can be mitigated by machining. Fractography analysis revealed that cracks were initiated at the WAAM-steel interface and microscopic observations showed that the microcracks were arrested by the porosities in the melted interface. Overall, this pioneering study highlights the promising potential of WAAM repair for combating fatigue damage in steel structures.

Summary: Light beams possess three types of angular momentum, namely spin angular momentum, extrinsic orbital angular momentum, and intrinsic orbital angular momentum. The interaction between these momenta leads to the spin-orbit interaction of light and topological effects. This study predicts a new topological effect resulting from the influence of extrinsic orbital angular momentum on spin angular momentum in converging asymmetrical light beams. It manifests as the transformation of linear polarized light into elliptically polarized light when an asymmetrical beam passes through the left or right half of the focal plane. The measured value of the topological circular amplitude anisotropy R was found to be R = +/- (0.60 +/- 0.08) x 10(-3). This new effect contributes to our understanding of light and has potential applications in developing sensors in optics.

However, the use of planar targets for coordinate measurement in vision systems has several drawbacks, including calibration difficulties and limited viewing angles. On the other hand, the use of sphere targets is infrequent in vision-based coordinate metrology due to the lack of efficient multi-view vision algorithms for accurate sphere measurements.
