To reduce the defects in laser welding of carbon fiber reinforced polymer (CFRTP) and aluminum (Al) alloy and improve the mechanical properties of the joint, a high speed rotational laser welding (HSRLW) technology was introduced. The mathematical model of CFRTP-Al alloy laser joining was established and the temperature was simulated. The weld depth of aluminum alloy and the penetration depth of CFRTP/aluminum alloy joint were calculated and compared with the experimental result. It was found that the pore defects can be significantly reduced, and a high strength joint could be obtained. The simulation results agree well with the experimental results, and the strength of the CFRTP/aluminum alloy joint can be predicted by using the numerical simulation method.

CFRTP-铝合金激光辅助高速旋转焊接技术

为了减少碳纤维增强聚合物(CFRTP)和铝(Al)合金的激光焊接中的缺陷并改善接头的机械性能,引入了高速旋转激光焊接(HSRLW)技术。建立了CFRTP-铝合金激光焊接的数学模型,并模拟了温度。计算了铝合金的焊接深度和CFRTP /铝合金接头的熔深,并与实验结果进行了比较。发现可以显着减少孔缺陷,并且可以获得高强度接头。仿真结果与实验结果吻合良好,采用数值模拟方法可以预测CFRTP /铝合金接头的强度。
