摘要
研究了用于快速成形的TIG熔敷堆焊工艺中各参数与焊缝宽度的关系。在大量试验的基础上,对TIG熔敷堆焊焊缝宽度进行数据分析,得出了在TIG熔敷堆焊情况下焊缝宽度的影响参数,提出了关于TIG熔敷堆焊焊接的规范措施。在较为规范的情况下获取TIG熔敷堆焊工艺中的焊接电流、送丝速度与焊缝宽度数据,选择BP神经网络进行焊缝宽度建模。从建模结果来看,基本上与试验的实际结果相符合。
The paper researches the relation of parameters and weld width of TIG deposit surfacing used in rapid prototyping. Based on a lot of experiments and the data of weld width of TIG deposit surfacing,influencing parameters of weld width and the criterial welding measure during TIG deposit surfacing are advanced. BP neural networks are used to model weld width. According to the welding current,wire feed rate and the weld width of TIG deposit surfacing advanced under standard conditions,the modeling results basically accord with experiment results.
