摘要
在激光塑料透射焊接理论的基础上,采用半导体激光器焊接聚碳酸酯(PC)塑料薄板,研究了激光焊接热塑性塑料的可行性。设计并确定了激光透射焊接的实验方案,包括激光器和焊接材料的选择。通过微观金相实验分析了焊接因素对焊接质量的影响。通过正交实验法研究了激光功率、焊接速度、炭黑含量对焊接质量的影响。结果表明对于聚碳酸酯材料而言,激光功率是影响焊接质量的首要因素,其次是焊接速度,最后是炭黑含量。
Abstract
Based on the theory of laser transmission welding, the feasibility of laser welding the polycarbonate (PC) sheet plastics is researched. The experimental scheme for laser transmission welding is plotted, which includes the selection of laser equipment and welding materials. Metallographic microscopy is conducted for experimental samples in order to investigate the influence of welding parameters on welding quality. Orthogonal experiment method is used to study the welding results under different conditions of laser power, welding speed and the content of carbon black in polycarbonate. The results show that the laser power is the primary influencing factor, followed by the welding speed, and the last is the content of carbon black.
