摘要
针对日益严格的技术、环境指标和交流焊接生产的管道无法应用于高品质工程的问题,利用中频逆变直流电阻焊原理,设计并实现了控制精度为0.001 s的高强度钢塑复合管道PLC控制系统。经过系统组态、焊接电路的设计和改进,与交流电阻焊相比较,直流焊焊点强度提高约20 kg,抗挤压能力提高约3.0MPa。试验结果表明,通过采取抗干扰措施,系统运行稳定可靠、通用性强、控制精确、操作方便。
This paper designed and realized high strength plastics-steel composite PLC controlling system with the precision of 0.001 s, utilizing the principle of mid-frequency inverter resistance welding,in accordance with the problems that composite pipe produced by AC resistance welding can＇t meet the application in high-quality project in face of the increasingly stringent technological and environmental indexes.The strength of welding point enhanced about 20 kg and the capability of anti-extrusion improved approximately 3.0 MPa in contrast with AC welding.The experimental results indicated that the system in the abominable electromagnetic environment is reliable, strongly universal ,accurate control and convenient operation.
