ABSTRACT
This copper aluminum tube welding process process and the
characteristic, the welding process process decomposition will be 6
movements, contains the movement is the translation, according to
the copper aluminum tube welding machine's practical work demand,
analyzes electric circuit's principle of work, designs the PLC
peripheral circuit, based on this, designs the complete control
procedure, and carries on the simulation debugging. Through the PLC
shaping, the PLC peripheral circuit's design, develops a copper
aluminum tube welding machine's control circuit, increased the
copper aluminum tube butt welding machine's timing precision, thus
realizes the copper pipe and the aluminum tube high grade
welding.
Key Words: Copper aluminum tube, welding, PLC
