基于DSP的一体化双丝脉冲MIG焊机软件设计
Software design of integrative twin-wire pulsed MIG welding based on DSP
摘要
Abstract
Twin-wire welding has much more advantages than single wire welding.Twin-wire is very efficient in welding and has a small heat input which can suit the big current circumstance.But because of its technical complexity,the research is only just beginning in China.the control system of integrative twin-wire plused power supply based on DSP chip TMS320F2808 was established in this article.Using an incremental digital PI algorithm welding current control.The overall power source testing was done on that platform,including the hardware testing and the software debugging.Then the static characteristics and the instant motive characteristics were both tested,which turned out to be a satisfaction of the Tandem system designed.With twin-wire pulsed MIG welding process for 8mm thick 45 steel, a series of comparative experiments is done, Including twin-wire pulse different phase. Finally good performances and beautiful Tandem welding seams came out,at the premise of the right parameters-matching of the two output pulses.关键词
