摘自清华大学机械工程系研究生陈 强的博士学位论文,导师:潘际銮 在焊接生产工艺方面的一个重要课题,是使工件在无衬垫条件下实现单面焊双面成型。由于不少容器受到尺寸、形状的限制,既无法在背面施焊,又无法在背面加衬垫。为此,MIG焊单面焊双面成型的焊接工艺正越来越受到重视。 本文阐述了MIG焊缝单面焊双面成型微机控制系统的基本原理和电路组成,设计了I/O接口电路, From Tsinghua University, Department of Mechanical Engineering graduate Chen Qiang doctoral dissertation, instructor: Pan Jiluan in the welding production process an important issue is to make the workpiece in the unlined condition to achieve single-sided welding double-sided molding. Due to the size and shape of many containers, there is no way to apply welding on the backside or back padding. To this end, MIG welding single-sided double-sided forming welding process is more and more attention. This paper describes the basic principle and circuit components of MIG welding single-sided welding double-sided forming microcomputer control system, designs the I / O interface circuit,
