摘要:基于提出的LB-RSW复合亚博vip4方法的基本概念,研究了“激光束—电阻缝焊(LB-RSW)”复合亚博vip4系统的结构形式和基本组成,自主研制了专用的多功能电阻缝焊机,并与Nd:YAG激光器和亚博vip4机器人组成了LB-RSW亚博vip4试验系统;工艺试验表明,LB-RSW比单独激光焊有更大的深/宽比和拉剪力,显着提高了激光对高反射率材料的加工能力和工程应用范围;进行了LB-RSW中RSW温度场和电流场的数值模拟和热成像测量。结果表明,数值模拟技术和红外热成像技术是研究复合亚博vip4过程的有效手段。

Abstract:Based on the fundamental concept of hybrid laser beam and resistance seam weldingLB-RSW,propounded by the authors,structure form and basic component of hybrid LB-RSW system was studied,and special multifunctional resistance seam welding machine was designed and manufactured independently,which constitutes the hybrid welding experimental system with NdYAG laser and welding robot.The experimental results indicate that,LB-RSW,which can achieve larger weld penetration depth/width ratio than that obtained by single laser beam welding,enhances the processing capacity on high reflectivity materials dramatically,thus it widens the application field of LB in engineering.Besides,numerical simulation of temperature field and electrical current field gained from RSW during LB-RSW was carried out,meanwhile,the temperature field was also measured using infrared thermography system.The results show that numerical simulation technology and infrared thermography technology are effective method to study hybrid welding process.
Key words:hybrid welding;laser welding;resistance seam welding;welding equipment;numerical simulation1
