Compared with conventional steels, press-hardened steels with an aluminium-silicon coating have a smaller welding range, which is resulting in reduced process stability. For this reason, an analytical methodology is required, which can optimise the welding parameters and extend the welding range significantly. Consequently, most publications focus on the variation of welding time and welding current at a constant electrode force. This paper deals with the design of a force profile to improve weldability and joint quality. The basis for this investigation is the identification of significant characteristic values by the recorded process signals.

可变电极力的电阻点焊—扩展了22MnB5 + AS150可焊性的测力曲线的发展和优势

与传统钢相比,具有铝硅涂层的加压硬化钢的焊接范围更小,从而降低了工艺稳定性。因此,需要一种分析方法,该方法可以优化焊接参数并显着扩展焊接范围。因此,大多数出版物集中在恒定的电极力下焊接时间和焊接电流的变化。本文讨论了一种力轮廓的设计,以提高可焊接性和接头质量。这项研究的基础是通过记录的过程信号识别重要的特征值。
