                                                    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.
