1.Automaticallyweld the square seam between the inside Partition and the tank body
2.For square welds, because the circumferential welds are irregular welds, the welding torch is required to walk the weld track, while ensuring that the welding specifications are as uniform as possible, the welds are beautiful in shape, easy to use, reliable, and the welding quality meets the requirements. .
3.The fuel tankrotates, the welding torch is moved left and right, forward and backward, and a short-distance wire pushing mechanism is adopted to ensure the stability of wire feeding.
4.The CNC systemand PLC control the rotation, left and right and forward movement of the welding torch, and walk out the welding seam trajectory to realize the normal welding of the square welding seam.
5.The welding power source has excellent arc starting, arc stabilization and arc closing performance to ensure uniform welding seam.
6.High-power AC servo motor and imported driver are used to control the rotation of the main shaft and the front and back, up and down movement of the welding torch.
7.Adopt MIG welding method to improve efficiency and reduce deformation.
8.The laser tracking mode is adopted to automatically track the welding seam and overcome the deviation of the welding seam.
9.Welding process
1 Manual loading the fuel tank which already assembled partition inside
2 the welding torch reach the welding position and supply the shield gas
3 start arc and welding straight line
4 reach the setting length, end arc and the welding torch lift up
5 the spindle chuck rotates 90°
6 welding torch move to the welding position and supply the shield gas
7 start arc and weld the second straight line
8 reach the setting length, end the arc and the welding torch lift up
9 spindle rotates 90°
10 welding torch move to the welding position and supply the shield gas
11 start arc and weld the third straight line
12 reach the setting length, end the arc and the welding torch lift up
13 spindle rotates 90°
14 reach the setting length, end the arc and the welding torch lift up
15 spindle rotates 90°
16 start arc and weld the forth straight line
17 reach the setting length, end the arc and stop supply shield gas
18 release the fuel tank from spindle shaft chuck tooling jig manually
