技术专栏 | 蓝光-红外复合激光为有色高反金属焊接提供高质量解决方案
焊接技术自工业革命以来，始终是制造业中不可或缺的核心工艺之一。从最初的手工焊接发展到如今的自动化激光焊接，焊接方法的进步推动了汽车、航空航天、电子设备及其他关键领域的快速发展。然而，随着材料科学的进步和产品设计的日益复杂，传统焊接技术开始显露出其局限性，尤其是在处理高反射金属（如铝和铜）时，焊接质量和效率之间的矛盾愈发突出：现有的激光焊接采用的激光通常为红外激光，由于有色金属在固态下对红外激光吸收率很低，在液态下吸收率会阶跃上升，导致在焊接过程中出现焊接不稳定、焊缝存在大量气孔和裂纹等问题，影响整体产品的性能和可靠性。同时，很高的反射性会使激光束在金属表面产生大量回反光，影响焊接设备的稳定性和寿命。
蓝光红外复合光源简介
在这种背景下，蓝光激光技术作为一种新兴的焊接解决方案，展现出了独特的优势：铜、金等有色金属对蓝光激光（波长约为450nm）的吸收率大大高于对红外激光的吸收率（铜对蓝光的吸收率是对红外激光吸收率的12倍、金对蓝光的吸收率更是比红外光高60倍）。更高的吸收率提升了有色金属的可焊性，提高了焊接效率，显著降低了能量损耗。

产品批量生产中的质量控制：Cpk大于1.33的重要性解析
Cpk过程能力指数是指过程能力满足产品质量标准要求（规格范围等）的程度。也称工序能力指数，是指工序在一定时间里，处于控制状态（稳定状态）下的实际加工能力。它是工序固有的能力，或者说它是工序保证质量的能力。它是每个质量人必备技能，它是衡量生产过程能力高低的数据，对质量管理、质量提升非常重要。

Cu/Al异种金属焊接的挑战与突破
铜铝异种金属激光焊接工艺面临两大核心挑战：一方面，铝和铜对激光的高反射率及物性差异导致激光吸收率低、焊接过程稳定性差；另一方面，焊接过程中Cu/Al元素的充分混合会促进脆性金属间化合物（IMCs）的大量形成，严重影响接头力学性能。
