Tank welding machines are actually transformers with lower external characteristics, which convert 220V and 380V alternating current into low-voltage direct current. Electric welding machines can generally be divided into two types according to the output power source. Therefore, tank welding machines can be divided into many types according to different characteristics.
Here is the content list:
l Tank welding machines are classified according to power characteristics.
l What types of tank welding machines does WINCOO have?
l What are the classifications of tank welding machines based on the market industry?
One type of tank welding machine is AC power and the other is DC power. A DC welding machine can be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer, and then rectified by the rectifier, and then outputs a power source with reduced external characteristics.
The output terminal will produce huge voltage changes when it is switched on and off the tank welding machines. When the two poles are short-circuited momentarily, the arc is ignited, and the generated arc is used to melt the electrode and welding material, and after cooling, the purpose of combining them is achieved. Welding transformers have their own characteristics. The external characteristic is the sharp drop in voltage after the electrode is ignited.
WINCOO provides automatic tank welding machines for tank manufacturing applications. Unlike other tank welding machines on the market, WINCOO AGW comes standard with a dual drive system and other features unique to our machines.
This automatic submerged arc welding system can reduce on-site tank welding time by 40% and reduce welding defects by increasing the arc on time. These models run directly on the fuel tank and carry the operator, eliminating the need for scaffolding, while ensuring the comfort and safety of the operator.
Due to the modular design, tank welding machines are suitable for single-wall or double-wall storage tanks constructed from top-down or bottom-up. Our design allows us to provide customized units for special applications.
EGW vertical gas-electric tank welding machines are highly efficient automatic welding equipment, which can control the improvement of the welding frame according to the current feedback closed loop. In a water-cooled forced welding seam, the main feature of a forming is the thickness from 10mm to 50mm.
The liquid level of the molten pool is automatically controlled, and the wire length is automatically adjusted. Small size, light weight welding frame and easy to update flexible modularization, easy to use. Widely used in petroleum, chemical, blast furnace thick plate welding and shipbuilding industries.

The hydraulic jack has strong supporting capacity, and the supporting force of heavy hydraulic jacks exceeds 100t.
What are the components of hydraulic storage tank lifting equipment?
What is the role of hydraulic storage tank lifting equipment?
What are the classifications of hydraulic storage tank lifting equipment?
Air filter: Prevent foreign debris from mixing, filter the air, and balance the pressure in the fuel tank and the atmosphere.
Oil level gauge: Used to observe the amount of oil in the tank. When the tow pump is working, the oil level must be above the middle of the oil level.
Thermometer: Displays hydraulic oil temperature.
Quick refill connector: used for filling of hydraulic oil.
Drain valve: It is used to remove dirty oil when the fuel tank is cleaned, and it is usually closed.
Hydraulic storage tank lifting equipment is a special container, in addition to storing hydraulic oil, it also has the function of dissipating heat and depositing grease. Therefore, in addition to cleaning the oil tank, the upper cover of the hydraulic oil tank cannot be opened casually, and an air filter is set on the oil tank to communicate the atmosphere with the air in the oil tank through the filter. Hydraulic oil tank is generally composed of quick refueling joint, air filter, thermometer, oil level gauge, oil suction self-sealing device, box body, drain valve and other main components.
Universal hydraulic storage tank lifting equipment is suitable for various lifting operations with small lifting height. It consists of oil chamber, oil pump, oil storage chamber, piston, crank handle, oil valve and other main parts. When working, as long as the crank handle is moved back and forth, the manual oil pump continuously presses oil into the oil cylinder. Due to the continuous increase of the oil pressure in the oil cylinder, the piston and the weight on the piston are forced to move upward together. Open the oil return valve, and the high-pressure oil in the oil cylinder will flow back to the oil storage chamber, so the weight and the piston will fall together.
The special hydraulic storage tank lifting equipment is a special tensioning machine, which applies tension to the prestressed steel bars when making prestressed concrete members. The dedicated hydraulic storage tank lifting equipment is mostly double-acting. There are two commonly used types: through-heart type and cone-anchor type.
The feed-through jack is suitable for tensioning steel tendons or wire bundles. It is mainly composed of a tensioning cylinder, a top-pressing cylinder, a top-pressing piston and a spring. Its characteristics are: there is a piercing hole along the axis of the stretching machine, and the steel bar (or steel wire) is anchored by the tool at the tail after being penetrated.
WINCOO ENGINEERING CO., LTD always focuses on customers’ needs and therefore it will provide the best hydraulic storage tank lifting equipment for all customers from all over the world. If you want to know more, please connect us.

At present, we have three types of hydraulic jacking system in WINCOO Engineering Co., LTD. They are the following three: Advanced hydraulic jacking system, Simple unfixing Holding -latch hydraulic Jacking system and Simple chain type hydraulic jacking system.
Hydraulic jacking system (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jacking system, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.
The following short description gives the working procedure in outline. It can in certain details be modified when required.
1.The tank bottom – plates are placed on the prepared foundation and welded together.
2.The beams or lattice work of the roof are assembled and finally joined to the upper rim of the shell ring.
3.The hydraulic jacking system is installed in the tank. The plates of the second shell ring (next to the top ring) are positioned outside the first one.
4.The completed part of the tank (roof and top shell ring) is lifted hydraulically to a height at which the plates of the second ring can be moved into place and the roof sheeting can be completed.
5.The plates of the second shell ring are located exactly and welded together to the lower edge of the first ring.
6.The plates of the third shell ring are placed outside the second shell ring.
7.The completed part of the tank (roof the two uppermost shell rings) is lifted.
8.The above cycle of operations is repeated until the last (bottom) shell ring is finished.
9.The entire tank is lowered down to the bottom plate and welded to this.
10.The lifting equipment is dismantled.
