It has formed sales network centered on Chinese Eastern Area and radiated to all big and medium cities in China and also exported to countries and areas such as Europe, America, Eastern Asia, and Africa and so on.Īt the same time, QINGDAO DUNIVERSE IMPORT AND EXPORT Co., Ltd as the Wholly-owned subsidiaries of DUNIVERSE (QINGDAO) HOLDING Co., Ltd. These products are widely used in many manufacturing fields such as cars, trains, ships, engineering machinery, pressure vessels, mineral machinery, bridge construction, agricultural machinery, electrical equipment and so on. It is the biggest welding wire manufacturing enterprise in eastern area in China and can produce 250, 000 tons of products every year. Flux is a mixture of various minerals, chemicals, and alloying materials that primarily protect the molten weld metal from contamination by the oxygen and. Its main products 'DUNIVERSE' brand has hundreds of specifications such as gas protection welding wire, submerged arc welding wire, flux-cored welding wire, argon arc welding wire, heat-resisting steel wire, atmospheric corrosion resisting welding wire, welding flux, carbon steel, stainless steel welding electrode, all kinds of welding flux and so on. This flux has less density than the metal to be welded. Flux-Cored Arc Welding (FCAW) uses the heat generated by a DC electric arc to fuse the metal in the joint area. The flux is present in the outer coating of the welding electrodes. 2) Weak Oxidizing Flux: This flux type has low content of active oxidant like SiO2, MnO, FeO. Welding Career Pathways prepares you to build on. There are two types: one type contains high content of SiO2, MnO, one type contains high content of FeO. Flux Core Arc Welding Certification Preparation, Career Pathway certificate. It is a modern private enterprise and specially engaged in developing and manufacturing welding wire. Welding flux is a combination of silicate and carbonate material which is used in the welding process to form a shielding layer which prevents the contamination of atmospheric gases with the weld. Welding flux can be categorized into three groups: 1) Oxidizing Flux: This flux is oxidable to weld metal. Belongs to DUNIVERSE (QINGDAO) HOLDINGS Co., Ltd. QINGDAO DUNIVERSE IMPORT AND EXPORT Co., Ltd is situated in Qingdao city, Shandong province which is built in 2004.
