Afterward, a single layer cladding was performed at the selected frequency to determine the microstructure and corrosion properties of the deposited cladding. The microstructure was characterized using optical and scanning electron microscopy, as well as electron backscattering diffraction. Corrosion tests were conducted to evaluate the pitting potential, critical pitting temperature, and weight loss, in accordance with current standards. The results revealed the absence of martensite with high hardness at the fusion line, an appropriate thickness, and Fe content lower than 10%. The austenitic microstructure, with a low fraction of Laves phase and NbC, exhibited suitable performance in the corrosion tests according to the applicable standards.

Still, good predictions of weld bead geometries are necessary for optimal planning of robotic welding. In the current work, a two-dimensional model for welding in a groove assuming parabolic weld bead profiles was established. The scale and orientation of the parabolas were determined from the welding parameters and direction of gravity. Another model employed a purely empirical neural-network approach, in which the bead profiles had a more flexible geometric parametrization consisting of a set of radial distances from the welding torch. This enabled the representation of more complex bead profiles. Calibration and validation of the two models were based on three welding tests with welding directions varying from 0 to 45° compared to the horizontal direction. The correspondence between the modeled and measured bead profiles was good for both models, with the neural network having the highest accuracy, especially in the transitions between bead and substrate.

High-speed photography reveals that within the groove, the pulsed laser generates a high-temperature zone ahead of the molten pool, surpassing the thermionic emission temperature. This stabilizes the cathode spot position, suppresses arc and droplet deflection, thus effectively inhibiting weld inclination. The weld inclination angle β is reduced from 30 to 2°, effectively solving the backing weld inclination problem and producing a concave weld conducive to subsequent welding. Furthermore, the pulsed laser modifies the droplet dynamics by altering the force state: the proportion of one pulse multiple droplets transfer increases from 10 to 29%, and the transfer frequency rises from 258.1 to 303.5 Hz, achieving uniform droplet transfer. Due to the enhanced molten pool fluidity of PLMW joints, pore defects are eliminated and grains are refined, thereby optimizing joint properties. Tensile tests confirm a joint strength of 965.5 MPa and an elongation of 12.92%, representing a 20.5% increase, with the fracture mode shifting from mixed ductile–brittle to fully ductile. These findings confirm that the PLMW process, when applied to the backing welding of medium-thick titanium alloys, can achieve significant improvements in weld formation and mechanical properties while maintaining the high deposition rate of MIG welding.</p></div>","PeriodicalId":809,"journal":{"name":"Welding in the World","volume":"70 8","pages":"3485 - 3503"},"PeriodicalIF":3.1,"publicationDate":"2026-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the acoustic signal distributions and variations during Ti-6Al-4 V laser oscillation welding process through numerical simulation. Firstly, a multi-physics thermal-fluid dynamics model was established to study the keyhole formation and dynamic evolution process. Then a keyhole acoustic field model was developed to analyze the sound signal distributions inside of keyhole and the variations of them under different keyhole dynamic shapes. The study found that under laser oscillation conditions, the attenuation of the sound pressure level inside the keyhole is more pronounced. It was also found that the sound pressure level is inversely proportional to the keyhole depth, although the irregular shape of the keyhole weakens this inverse relationship. Furthermore, as the laser oscillation frequency increases, this weakening effect becomes progressively more evident.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":809,"journal":{"name":"Welding in the World","volume":"70 8","pages":"3831 - 3849"},"PeriodicalIF":3.1,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially for the production of small series, prototypes, or individual parts, economical production alternatives can be expected due to the near-net-shape component structure. Approaches for higher efficiency of the component cooling during the build process indicate the potential for increasing the productivity of wire arc directed energy deposition (DED-Arc). Moreover, the control of the cooling rate is of interest for the processing of materials with low thermal diffusivity such as high-alloy steels. Therefore, in situ component cooling in DED-Arc additive manufacturing using a cooling gas flow is discussed in this article.

Based on these, a selection of derived design concepts for cooling gas nozzle sets is demonstrated in the present study.

Considered is capacitor discharge welding of sandwich structures from two sheet metals with an interlayer of wire mesh. The intersection points of the individual loose wires form natural projections for the applied projection welding and are used for current concentration. Through the regular arrangement of projections, many individual welds with locally low heat input are created within a single pulse, which leads to a quasi-planar joint area. During the process, for each crossing point, the loose wires are welded together and the joining to the upper and lower cover sheet is also carried out. The aim of this work was to maximize the shear tensile force as a target value by varying the electrode force and energy and to identify correlations. Within the investigations, the influence of the wire mesh materials was analyzed in the form of ferritic as well as low-alloy steels. In addition, the geometry of the wire mesh was investigated by considering the wire diameter and the number of projections with respect to joint formation and joint quality. An optimized number of 50 projections were determined with shear tensile forces above 40 kN for a X6Cr17 wire mesh. With larger connection surfaces, a wire diameter of 1.2 mm proved advantageous compared to 1.0 mm. The higher-density wire material X6Cr17 required less energy compared to C9D for comparable heat inputs into the joints. Target weld areas were identified and welding parameter recommendations provided.</p></div>","PeriodicalId":809,"journal":{"name":"Welding in the World","volume":"70 7","pages":"3023 - 3042"},"PeriodicalIF":3.1,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
