Abstract

In metal welding processes, micro-electromechanical system (MEMS)-based thermoelectric infrared sensors are widely employed for real-time temperature monitoring to ensure weld quality. However, welding by-products, particularly fumes and molten metal spatter particles, introduce significant measurement errors in these sensors. This study investigates the mechanistic interaction between welding by-products and MEMS sensor performance, followed by systematic experimental analysis under varying operating conditions (object temperatures:

$30~^{\circ }$

C–

$110~^{\circ }$

C; measurement distances: 10–40 cm). A novel characterization method is proposed using binary classification of spatter-induced filter screen damage to quantify particle impact severity. Furthermore, a mathematical model is developed to correlate measurement error with temperature and distance variables, enabling real-time error compensation for by-product interference. Experimental validation demonstrates that the proposed compensation compensation algorithm reduces temperature measurement errors by up to 80.9% in high-spatter welding scenarios, demonstrating its practical utility in enhancing sensor reliability for industrial applications.

金属焊接副产物对mems热电红外传感器测温的影响

在金属焊接过程中，基于微机电系统（MEMS）的热电红外传感器被广泛用于实时温度监测，以保证焊接质量。然而，焊接副产品，特别是烟雾和熔融金属飞溅颗粒，在这些传感器中引入了显着的测量误差。本文研究了焊接副产物与MEMS传感器性能之间的相互作用机制，并在不同的工作条件下进行了系统的实验分析(物体温度：$30~^{\circ}$ C - $110~^{\circ}$ C；测量距离：10-40厘米)。提出了一种基于二值分类的飞溅滤网损伤表征方法。此外，建立了测量误差与温度和距离变量相关的数学模型，实现了对副产物干扰的实时误差补偿。实验验证表明，提出的补偿补偿算法在高飞溅焊接场景下可将温度测量误差降低80.9%，证明了其在工业应用中提高传感器可靠性的实用价值。
