Special Issue Information

Dear Colleagues,

Laser welding and cladding of compatible and/or non-compatible materials is one of the most important and effectively used technologies in different industries (aerospace, automotive, defence, etc.) by providing functional coatings to mechanical parts. The end quality of laser-welded and cladded parts depends on several factors, such as process parameters, materials, and process environment. Since several developments have been observed in different aspects of the laser welding and cladding process (new defect detection and prediction methods, enhanced laser capabilities, new process parameter optimization methods, different machine learning algorithms, etc.) in recent years, it is very important for scientific and engineering societies to share their studies, findings, and learnings to help improve the knowledge about these processes. 

Thus, we encourage you to submit your original research studies based on experimental data and/or numerical simulations and review articles to this Special Issue, titled “Laser Welding and Cladding: Recent Developments”. The topics of interest for this Special Issue, in particular, include (but are not restricted to) the following:

  • Laser welding and cladding of non-compatible new groups of materials;
  • New methods for enhancing wear resistance of laser cladding coatings;
  • New defect detection and prediction methods for laser welding and cladding;
  • Machine learning applications in laser welding and cladding;
  • Multi-objective optimization methods for process parameters;
  • New advancements in high-speed laser welding and cladding;
  • Laser welding and cladding applications in aerospace, automotive, and defense industries;
  • Laser welding and cladding in different environments;
  • Any other aspects of laser welding and cladding.

To mitigate welding defects in copper wire conductors induced by their high laser reflectivity and thermal conductivity during laser welding, this study combines numerical simulation and experimental testing to investigate the influences of laser processing parameters on the mechanical properties, molten pool dynamic evolution, and microstructural characteristics of copper self-fusion welds and pure Ni powder-filled welds. The results demonstrate that, for self-fusion welding, a moderate increase in laser power and welding time elevates the heat input, which promotes weld penetration and forming quality. The optimal parameter combination (3900 W, 1.0 s) yields a balanced internal densification and grain refinement, with the joint tensile strength reaching a peak of 245 MPa. For Ni powder-filled welding, the infinite solid solubility between Cu and Ni improves interfacial metallurgical bonding. Under the optimal parameters (3500 W, 1.2 s), the joint tensile strength increases to 282 MPa. Heat input exerts a significant effect on the temperature field evolution in both welding processes, yet the molten pool expansion behaviors differ: self-fusion welding exhibits continuous expansion with rising heat input, whereas Ni powder-filled welding displays complex nonlinear variations.
