CNC Girth Seam Welding Machine For Stainless Steel Tank
Tank girth welder is an automated welding equipment specially used for welding the circumferential seams of cylindrical workpieces (such as storage tanks, pressure vessels, pipes, barrels, etc.).
Description
CNC Girth Seam Welding Machine for Stainless Steel Tank
I.Description
Circumferential welding of tank bodies is a critical process for the manufacture and assembly of cylindrical or spherical tanks. This process is typically performed with the workpiece rotating or the welding torch circumferentially, using efficient methods such as submerged arc welding and gas shielded welding to ensure a uniform, dense, and high-strength circumferential weld.
II.Basic Design
- Welding torch is fixed while workpiece rotating. Welding position is horizontal. The workpiece is clamped tightly by jig at two ends and rotates.
- Two welding torches and two power sources work simultaneously to improve work efficiency.
- Torch, spindle box and tailstock can be adjusted longitudinally to fit various kinds of welding.
- Japan Omron PLC is adopted to control the machine to run and speed is adjusted by AC servo, which can improve the reliability of the equipment.
- Adopts end face positioning and pneumatically clamping mode.

CNC Girth Seam Welding Machine for Stainless Steel Tank
1.This machine is made up of mainframe, spindle box and its pneumatic feeding mechanism, tailstock and its pneumatic feeding mechanism, workpiece supporting mechanism, welding torch feeding and adjusting mechanism, electrical control system, pneumatic system and welding power source.
2.Tailstock Clamping Mechanism
The pneumatic tailstock can be adjusted along the guide rails to meet the requirements of various kinds of welding. It adopts hand-operating screw rod to adjust. The workpiece is clamped pneumatically and rotates. The extension of the tailstock equipped with pneumatic fixture. The fixture clamps two ends of the workpiece tightly to ensure the uniformity of every clamping.
Machine base is made of cast iron and thick steel tube. Guide rails are installed on the base.
3.Workpiece Supporting Mechanism
The left and right sides of the machine installed V-shaped brackets to support the workpiece. The V-shaped brackets move up and down pneumatically, move up when clamping and move down when welding.
4.Electrical Control System
Japan made PLC is used as the core to control the clamping and welding programs. The system has a good stability and simple structure, which is easy to maintain.
5. With oscillator and TIG arc tracking
