Abstract

Laser welding enables new designing prospects of highly effective electrical machines. This paper presents fundamental investigations concerning the weldability of electrical steel, and an approach for the mechanical characterization of the weld seam. Through an integrated view of the independent variables: process, design and material, the limits of weldability could be expanded. Moreover a significant increase in material strength due to the laser welding process is shown. These perceptions provide fundamental insight for the design of weld seams on electrical steel laminations.
电钢堆的激光焊接可焊性研究
激光焊接为高效电机的设计开辟了新的前景。本文对电工钢的可焊性进行了基础性的研究,并提出了焊缝力学表征的方法。通过对工艺、设计和材料等自变量的综合考虑,可以扩大可焊性的限制。此外,由于激光焊接工艺,材料强度显着增加。这些认识为电工钢片焊缝的设计提供了基本的见解。
