Traditional aluminum alloy≠₹ welding process: large prλ$ <oduct deformation, s¥§ ★low welding speed and low prod∏∞uction efficiency. Due to large welding¥γ deformation, subsequent correc§σ☆↑tion work often wastes a lot of timεσ♦πe, which increases manufacturing costs<<₹ and affects production efficiency a​$nd production quality. The laser≠↕‌ welding machine has high power d₩δα ensity, fast speed, low welding heat iλ₹δ♥nput, and welding heat. The  ¥™influence area is small, the w×♦elding distortion is sm∞•all, the weld seam is '±flat without pores, no or simple proces↔™→sing is required after welding, it can ‍<™εbe accurately controlled, the positio←↑ning accuracy is high, an±≠<d automatic laser welding can be realiz☆¥ ed.
