摘要
介绍了TIG焊快速制造金属体成形过程及特点,通过对金属体各层金相组织特点及形成原理的分析,提出了一种基于红外测温仪的TIG焊快速制造神经网络-PID温度控制系统,并介绍了该系统的结构组成及工作流程。试验证明,该系统的使用结合表面金属无丝焊热处理,能有效地提高整体金属体的性能。
The molding processing and characteristic of metallic object by TIG welding rapid prototyping were introduced.The characteristics and formation principle of the microstructure in every metallic layer were analyzed.A kind of infrared thermometer TIG welding rapid prototyping neural network-PID temperature control system was put forward.The structure composition and work flow of system were introduced.In experiment,the overall performance of metallic object was effectively improved due to the temperature control system and metal surface welding without wire.
