AI Technical Summary
Existing butt welding of thick aluminum alloy plates presents challenges such as mutual interference of electric arcs, poor fusion of narrow-gap GTAW sidewalls, and contradictions in deposition efficiency. Deformation control is particularly challenging in the welding of long components.
The double-sided magnetron welding process is adopted. Through the coordinated control of the two-sided magnetic fields, the front magnetic field focuses on stirring the molten pool and wetting the sidewalls, while the back magnetic field focuses on arc compression and interference suppression. The two-sided magnetic fields work synchronously according to the preset phase difference and frequency relationship, so as to realize the active control of the coupling behavior of the double-sided arc.
It effectively suppresses electromagnetic interference from the electric arc, improves arc stability, reduces welding deformation, improves sidewall fusion in narrow gaps, reduces porosity, and improves welding efficiency and quality.
