Automatic welding Machine Features

1.Automatic weld the circular seam of the round nozzle one the flat tank body (not include the nozzle at the corner)


2.The welding torch can be adjusted up and down, left and right and angle at a certain angle, the workpiece is fixed, and the welding torch rotates to weld.


3.The workpiece is positioned at the center by the tooling jig to ensure that the welding seam position does not shift, and there is no need for spot welding in advance.


4.The special machine has the function of high voltage, slow wire feeding and arc starting to ensure reliable arc starting. The function of closing the arc with small current and filling the crater.


5.Use Japan OMRON PLC to control and achieve the welding process, improve reliability.controls the whole machine operation. stable control and stable programming interface.


6.Welding torch can adjust Three-dimensional direction to suitable different size workpiece. it can be locked after adjustment.Machine has good operating performance and low failure rate.


7 Integrated control panel box. The control buttons, touch screen, welding specification control, etc. are concentrated on one panel, which is easy to use and operate.

Basic control functions of control panel

1.Control the rotating axis rotating speed ,up and down


2.Control Welding start and stop


3.Control wire feeding


4.Welding/simulation function


5.Program storage, modification and recall function


6.Reset the machine


7.The welding length adopts the closed-loop detection of rotary encoder, and the position detection such as: the torch position is detected by imported non-contact switch.

Working Procedures

1.Loading the fuel tank and nozzle on tooling jig of the support axis manually


2.Rotation axis move down to fix fuel tank and nozzle automatically

3. Welding torch go down automatically and Supplying shielding gas automatically


4. Automatic weld seam as the program automatically

5.Welding torch lifting up and go back to the original point automatically


6. Release Fuel tank from positioning tooling jig manually
