Flux Cored Wire:
Flux cored wire is also called powder-cored wire and tubular wire. It is divided into two categories: gas-entrained and non-gas-protected. The surface of the flux cored wire is the same as that of the Solid Wire and is made of materials such as low-carbon steel or low-alloy steel with good plasticity. The manufacturing method is to first roll the steel strip into a U-shaped section shape, then fill the U-shaped steel strip with solder powder prepared according to the dosage, roll it tightly with a rolling mill, and finally draw it into welding wires of different specifications.
Flux cored welding wire is a promising new welding material.

Recently, FAW Eaton Transmission Co., Ltd., a joint venture between FAW Group and Eaton USA, was officially unveiled in front of the original transmission branch. Assistant Governor Xu Jianyi of Jilin Province, Zhang Anshun, Vice Mayor of Changchun City, Yan Yanfeng, General Manager of FAW Group, Zhao Fangkuan, Secretary of the Party Committee, and Mr. Jim Sweitner, Senior Vice President of Eaton Corporation and President of the Truck Division, inaugurated FAW Eaton Transmission Co., Ltd. Xu Jianyi, Assistant Governor of Jilin Province, Dong Chunbo, Deputy General Manager and Chairman of FAW Group, and Paul Frank, General Manager of FAW Eaton Transmission Co., Ltd., addressed the ceremony. The First Auto Group Company and the Eaton Corporation of the United States have negotiated for 5 years and signed a "Joint Venture Contract" in Changchun on March 31 this year. After joint efforts of both parties, they finally cooperated with each other today. The project has a total investment of 100 million U.S. dollars and registered capital of 57 million U.S. dollars. In addition to continuing to produce FAW's existing and well-developed series gearboxes, the JV’s products will also introduce production and sales of Eaton’s best-selling and newly developed transmission gearboxes in the global market. These products have advanced synchronizer technology and more torque. Large, wider product series, better quality reliability and durability, torque from 530Nm to 1800Nm or more, gears are 5, 6th, 7th, 8th, 9th, and 10th, forming a high and low end. There are a total of seven product series with more than 600 varieties of product platforms, which can not only meet the needs of current FAW vehicles and replacement vehicles, but also provide FAW trucks and passenger cars with high-quality gearboxes, and can obtain a steady stream of technologies and products from Eaton Corporation. With support, some products are sold at home and abroad, and the ability to participate in domestic and international market competition is strengthened.
(1) Advantages:
1) For the welding of various steel materials, it is very convenient and easy to adjust the composition and proportion of the flux (the general-purpose flux-cored wire is often called the additive as the flux core, and the term flux only appears in the specific flux-cored wire). Requested weld chemistry can be supplied.
2) The process performance is good, and the welding seam is beautifully formed. Combined protection with gas slag is used to obtain good forming. The arc stabilizer is added to stabilize the arc and the droplet transfer is uniform.
3) Fast deposition speed and high production efficiency Under the same welding current, the flux-cored wire has high current density and fast melting speed. The deposition rate is about 85%-90%, and the productivity is about 3-5 times higher than that of electrode arc welding.
4) Larger welding current can be used for all-position welding.
(2) Disadvantages
1) The welding wire manufacturing process is complicated
2) When welding, wire feeding is more difficult than solid welding wire
3) The appearance of the welding wire is easy to rust, and the powder is easy to absorb moisture, so the requirements for the storage and management of the flux-cored welding wire are more stringent
