Introduction
Tank Circular Seam Welding Machine is an automated welding machine designed specifically for circular tank welding. It is suitable for metal tanks with a diameter of 200-700mm and a thickness of 3-5mm. It is widely used in the production of pressure vessels, liquid storage tanks and engineering machinery accessories.
PRODUCT DESCRIPTION
Main Features
High-Precision Welding
The equipment utilizes a 0.75kW servo motor drive, combined with a stable Chinese NBC-350A welding power source, for precise control of welding speed and current, resulting in uniform welds.
Wide Compatibility
Supports welding of tanks with diameters ranging from 200-700mm and lengths up to 2000mm, covering thicknesses of 3-5mm.
Easy Operation
Adopting a 220V single-phase input voltage and equipped with an automatic wire feed mechanism, it is easy to operate.
Energy-Saving and Stable
The servo drive, combined with 1.0/1.2mm solid wire, provides high energy efficiency and reduces consumables consumption.





Applications
Widely used in the production of circumferential seam welding of metal tanks:
Hydraulic oil tanks: Mass production of hydraulic oil tanks for construction machinery, excavators, and forklifts.
Gas tanks: Welding of gas tanks for automotive air brake systems and air compressors.
Fuel tanks and small containers: High-precision welding of generator set fuel tanks, small liquid storage tanks, etc.

FAQ
Q: What thickness of tank can this machine weld?
A: It's suitable for metal tanks with a thickness of 3-5mm, a common thickness range for gas storage tanks, hydraulic oil tanks, and other applications.
Q: Can ordinary workers operate it?
A: Yes. The equipment is highly automated, and users can start working after just one or two days of training. Highly skilled welders are not required.
Q: What are the power requirements?
A: The equipment's input voltage is 220V single-phase, 50Hz, and the welding power source is 380V three-phase, 50Hz, suitable for most factory power conditions.
Q: What support can you provide for wholesale purchases?
A: We provide one-stop technical training, installation and commissioning guidance, and guarantee a one-year warranty on core components. OEM customization is also supported.
Q: Is the cost of use high?
A: Not high. The equipment uses solid wire, which offers high energy efficiency, long-term stable operation, and low maintenance costs.
Q: What is the approximate production capacity?
A: Depending on the workpiece size and operating schedule, each machine can weld 100-200 circumferential seams of tanks per day, making it suitable for mass production.
