This study develops a laser-TIG hybrid welding process with homogeneous Al-Zn-Mg-Cu filler wire to overcome cracking and strength loss in 7075 aluminum alloy. The synergistic heat source enhances molten pool convection and element uniformity, promoting twinned dendrites and η′ precipitate strengthening. The resulting joints achieve 475 MPa tensile strength—80.8% of the base metal—significantly outperforming traditional methods.

Laser oscillation welding enables path-based energy programming by selecting and tuning oscillation patterns like Zig-Zag, Sine/Cos, figure-eight, or spiral to shape molten-pool behavior and weld quality. Different modes offer unique energy distribution mechanisms—e.g., figure-eight excels in stirring and porosity suppression, while spiral suits circular seam control and temperature sequencing. Coordinating oscillation amplitude, frequency, and speed allows engineers to customize weld penetration, sidewall fusion, and defect mitigation for diverse welding challenges.
