Tank, storage tank welding technology at home and abroad overview of large floating roof tank, storage tank, storage tank construction, widely used in automatic welding technology,technology has been quite mature. Our country has brought in a large tank in in the early 80 century, tank automatic welding technology and equipment, some equipment isachieved domestically. But in the dome tank, tank construction, electric arc weldingelectrode is mainly used in home, automatic welding is seldom used. At present, storage tank, tank construction most used welding methods are manual arc welding and automatic submerged arc welding (including horizontal welding, flat, angle welding), followed by CO2electrogas welding. In addition, CO2/MAG gas solid core or flux cored wire protectionautomatic welding and semi automatic welding has been used, but the application range is relatively narrow.

Storage tank, arc welding tank

Domestic dome tank, storage tank welding at present still with SMAW, especially 10000 m3 and below the tank, storage tank welding, commonly used by the construction units. The main reason is: this kind of storage tank, tank plate is relatively thin, and the use of flip chip assembly by welding, arc welding has the advantages of convenient construction,flexible, and small welding deformation, welding equipment, low investment cost, auxiliarysmall workload. Compared with the automatic welding, the overall economic benefit is better, but the personnel cost, high labor intensity, high personnel costs. For large floating roof tank, tank construction welding, arc welding is still accounts for a large proportion,especially storage tank, storage tank tank floating roof tank wall plate, weld, the solid and the attachment point welding, automatic welding can not replace the arc welding.
