提出了一种适用于不同激光透射焊接工艺的轴向测温方法。提出了一种适合于激光透射焊接要求的仿形准同步焊接温度检测方法,并给出了相应的温度场分布。对于实验,高温计连接到具有非颜色校正透镜的扫描器光学器件。实验采用高速高温计在1.65 - 2.1μm光谱范围内进行检测。评估由测量方法引起的潜在误差,并通过在焊缝中创建不同的缺陷来检查其取决于所执行的焊接技术的限制。
An on-axis pyrometric-based temperature measurement method suitable for different laser transmission welding techniques is presented. A temperature detection during contour and quasi-simultaneous welding is demonstrated to fit the requirements of laser transmission welding with part adapted temperature fields. For the experiments a pyrometer is connected to a scanner optic with a non-color-corrected lens. The experiments are performed with a high-speed pyrometer detecting in spectral range of 1.65 - 2.1μm. Potential errors caused by the measurement method are evaluated and its limits depend on the welding technique performed are examined by creating different defects in the weld seam.
