Aluminum Fuel Tank MIG Automatic Welding Machine
1.Design Mission
To complete the automatic square seam welding of fuel tank. For the
square welding seam, its welding seam is irregular, so the welding
torch is required to walk out of welding seam path. Meanwhile, it
should guarantee that the welding specification is as even and
uniform as possible. The welding seam appearance is good and
smooth. It is convenient and reliable to use machine.
2.Design Conception
1.Welding torch moves up-down, forward-backward to coordinate with
workpiece rotation. Adopt short-distance push type wire feeding
mechanism, to ensure the stability of wire feeding.
2.Adopt CNC system to control 3-dimension actions of workpiece
rotation and welding torch movement in up-down and forward-backward
direction. Welding torch walks out of welding seam path when the
arc is burning continuously, to realize the normal welding of fuel
tank square seam
3.Rotation speed is varying with the workpiece rotation position,
to make sure the welding linear speed is the same.
4.In the workpiece rotation process, the distance and angle between
welding torch and workpiece does not change.
5.Welding power source has good performance of arc igniting, arc
stabilizing and arc ending, to ensure that the welding seam is even
and uniform.
6.High power AC servo motor and driver control the rotation of
rotary axis and welding torch forward-backward&up-down
movement.
