Abstract
本发明属于3C新能源产品制造技术领域，公开了一种超薄微尺寸极柱环形激光焊接熔深表征及质量提升方法。采用环形激光焊接系统和CCD同轴定位系统，搭建精密焊接平台，以3C新能源产品常用3系铝合金超薄微尺寸极柱与盖板作为焊接基材，明确适配该类极柱的激光焦点定位方式与核心焊接工艺参数区间，并建立专用熔深评价流程及判定标准。本发明通过优化环形激光焊接工艺参数、标准化焊接作业流程，并配套专用熔深评价工艺体系，解决现有激光焊接技术应用于该类极柱加工时存在的技术瓶颈；解决了超薄微尺寸极柱因结构尺寸小、壁厚薄所引发的熔深均匀性差、工艺窗口狭窄、焊缝缺陷率高、焊接精度偏低，以及熔深评价精准度不足、工况适配性差等行业技术难题。
