The LNG head welding special machine is a device used for welding LNG heads, featuring unique functional characteristics.

The functional features of the LNG1100-MIG internal head automatic welder give it broad application prospects in the industrial manufacturing sector. It is hoped that through this introduction, everyone can gain a better understanding of it.

Functional features of the LNG1100-MIG internal head automatic welder:

1. Adapts to the accessible positions of the welding torch for circumferential seam welding of the LNG lower head-reserve chamber and upper head-front support outer tube assembly.

2. Suitable for welding various materials such as carbon steel, low-alloy steel, and stainless steel.

3. Equipped with MIG welding equipment.

4. Integrated machine design with a compact structure; includes a quick clamping mechanism.

5. The control system uses a large-screen touchscreen human-machine interface for easy programming.

6. The welding process storage capacity is 30 sets, allowing direct calling of the corresponding welding process by number based on the weldment specifications.

7. Standard equipped with a welding torch transverse oscillation system (OSC).

8. The chuck rotation is driven by a stepper reduction motor, enabling speed and position control.

9. Forced circulation water cooling system ensures long-term reliable operation of the machine.

10. One-button operation automatically completes the entire welding process; real-time intervention in welding parameters is also possible as needed.
