Tank welding machine is a machine used to weld the steel plates of large storage tanks.Large storage tank is a kind of tank used to store oil, natural gas and other energy.
The tanks were too big to form at once, so they were welded together with steel plates.
Manual welding is the simplest and most direct method, but because of its high cost and low welding speed. So in the splicing process automatic welding machine equipment has been widely used.
At present, automatic welding technology is widely used in the welding process of large floating roof storage tanks in China, including vertical carbon dioxide shielded welding for vertical seam of tank wall, submerged arc transverse welding machine for circular seam of tank wall, submerged arc automatic flat welding for lap fillet welding and large fillet weld of tank bottom.Transverse seam submerged arc welding is a special form of ordinary automatic submerged arc welding. It is used to weld transverse horizontal straight welds and transverse horizontal girth welds. It uses small welding power supply, arc voltage and high welding speed to obtain the weld forming in the transverse direction.This machine adopts flat characteristic welding power supply, equal speed wire feeding mode, reverse connection.The welding principle is the same as the common submerged arc welding, the main difference is to solve the problem of molten metal and flux drip automatic welding machine layout.
The welding machine equipment is composed of three parts: electric control system, hydraulic system and horizontal sensing system.The electrical control system consists of a general electric control console, a local control console and an electric control cabinet.The level sensing system, each equipped with a level monitor chopper, automatically and uniformly monitors and controls the overall level precision tank rise during jacking.The hydraulic system consists of several small pump stations and a hoist, etc. (a small pump station with a hoist).Local small electric cabinet systems with electrical controls are installed in small pump stations and can be operated independently or with local manual operation on the hopper (usually adjusted separately during sewing).It can realize the overall synchronous lifting, small volume adjustment of single jack bucket, automatic jack gravity.Cooperate with automatic welder to complete the automatic welding and installation of large storage tanks.

1.Large vertical steel storage tank is an important oil and product storage and transportation equipment in petrochemical industry. Welding is the main process of tank construction, which is of decisive significance to the construction quality and progress.

 

2.In petrochemical enterprises for product containers, generally is a large atmospheric vault storage tank, the current development trend, this kind of tank is bigger and bigger, in manufacturing this kind of large storage tank construction difficulty is becoming more and more big, mainly for welding work harder, welding workload increase, about 50% of the total quantity, therefore, many large sized manufacturing enterprises have taken a variety of technologies. To improve welding efficiency and ensure welding quality, tank welding machine is one of the most effective technical measures.

 

3. In order to save time and reduce labor costs, tank welding machine have become the best choice for many tank contractors.
