摘要
研制了 1套以 80 98单片机为核心的晶闸管整流焊机的控制系统。通过闭环反馈及PID算法实现了焊机的双阶梯形外特性。控制系统工作稳定可靠、抗干扰能力强 ,最大输出电流为 10 0 0A。该焊机可以满足TIG焊、手工电弧焊、碳弧气刨及埋弧焊等多种焊接方法的工艺需求 。
A thyristor arc welding rectifier controlled by 8098 single chip microcomputer is developed. The double steps external characteristic of the welding rectifier is realized by closed loop feedback and PID arithmetic.The control system work well and have strong ability against disturb.The largest output current is 1 000 A.Using the welding rectifier many welding process,for example the TIG welding,manual arc welding,carbon arc air gouging and submerged arc welding et al,can be done well.
