Copper Laser Welding Solutions
Pursuing Peak Efficiency and Zero Defects
Due to their superior electrical conductivity, copper and its alloys (such as pure red copper and brass) serve as core components in electric vehicles, semiconductors, and power electronics. However, copper’s high reflectivity to lasers often causes unstable energy absorption, severe spatter, and poor weld seam formation. Through industry-leading optical configurations and real-time monitoring technology, Laser Mech Taiwan helps clients overcome the processing barriers of highly reflective materials.
KEY TECHNOLOGIES
The Perfect Synergy of AMB and LDD
IPG AMB Technology—The Key to Eliminating Spatter
Utilizing advanced IPG's AMB (Adjustable Mode Beam) laser technology, we dynamically stabilize melt pool dynamics by independently adjusting energy between the core and ring beams. This beam shaping technology significantly suppresses spatter during welding, resulting in smoother weld profiles and virtually porosity-free internal microstructures.
LDD Real-Time Weld Depth Tracking System—Digital Quality Assurance
To ensure every weld seam meets rigorous power transmission standards, we recommend integrating the LDD (Laser Depth Dynamics) system. This system provides real-time depth measurement with micron-level accuracy during the welding process, enabling 100% process monitoring. It not only addresses the key industry pain point of "invisible depth" in copper welding, but also automatically logs data to serve as digital documentation for quality traceability.
In battery terminal and busbar processing, Laser Mech Taiwan solutions achieve stable deep penetration welding through precise energy distribution control. This ensures weld seams deliver extremely low contact resistance and high mechanical strength, fully meeting the rigorous demands of high-current transmission.
