Composite Metal Welding

Precise preheating to break the "reflection shield"： The 980nm semiconductor laser acts first, precisely softening the oxide layer on the material surface and significantly reducing the material's reflectivity to subsequent laser energy.

Stable deep penetration, building a "perfect welding pool"： The 1070nm high-power fiber laser focuses and penetrates instantly. Under the "friendly window" created by the 980nm laser spot, it achieves efficient energy absorption and forms a stable and controllable deep penetration welding pool.

Intelligent collaboration, breaking through performance limits： The two laser beams achieve intelligent matching in terms of time, space, and energy distribution, dynamically adapting to different working conditions (such as thickness variations and gaps). This perfectly suppresses spatter and porosity, resulting in weld seams that are aesthetically pleasing, consistent, and free of internal defects.

Core Value — Significantly Improving Product Processing Yield

Say goodbye to "cold soldering" and "porosity"： The dual-beam collaborative mode fundamentally addresses the core pain points in welding highly reflective materials, resulting in weld seams with high density and excellent mechanical properties.

Process Quality Monitoring System：The equipment integrates the self-developed Process Quality Monitoring System by Weikerui. Through quantitative monitoring of various indicators of the laser and metal molten pool during the welding process, it can identify molten pool defects online.

Greatly Reduces Spatter： The controllability of the welding process is significantly enhanced, resulting in clean product surfaces, reduced post-welding cleaning processes, and improved overall efficiency.

Wider Welding Range： It has higher tolerance for assembly gaps and material surface conditions (such as micro-oxidation), and stronger adaptability.

High Process Stability： Intelligent process control ensures the stability and consistency of mass production.

Industry Preference — Widely Used in Precision Manufacturing

Precision Manufacturing of In-Vehicle Cameras： The precision joining of key components such as aluminum alloy housings, brackets, and heat sinks ensures the long-term stability and sealing performance of sensors in high-vibration, high-and-low-temperature environments, thereby enhancing the reliability of core components for autonomous driving.

Core Processes of New Energy Batteries： High-quality welding applications such as the welding of aluminum alloy housings for power battery packs, the welding of Busbars (copper-aluminum connecting sheets) in battery modules, and the welding of battery cell tabs (especially for highly reflective aluminum materials) directly enhance the safety, reliability, and energy density of battery packs.
