Description
Product Description
J421 AWS A5.1 E6013
Rutile Type Electrode ISO 2560-A-E35 0 RA 12
GB/T 5117 E4313
Applications:
It is suitable for welding of low carbon steel structure, especially for the welding of thin plate steel with short discontinuous weld and requirement of smooth welding pass.
Characteristics:
J421 is a rutile type electrode. Can be welding by both AC & DC power source and can be for all-position. It have excellent welding performance as stable arc, little spatter, easy slag removal and reignition-ability etc.
Attention:
In generally, don't need to re-dry the electrode before welding. When it be affected with damp, should be re-dry it at 150℃-170℃ for 0.5-1 hour.
Welding Positions:
PA, PB, PC, PD, PE, PF

Company Profile
In 1950s, our products were used for the project of Wuhan Yangtze River bridge. It was the first time that domestic welding consumables used in Chinese key project. In order to commemorate this honor, "BRIDGE" brand was born. We established the group company in 1992.
In 2013, a new and modern welding consumables industrial park (here) was established.
Our new industrial park is total one million and two hundred thousand square meters, including welding electrode factory, solid wire factory, flux cored wire factory, and welding flux factory, and other series of supporting enterprises. The annual production capacity is one million and five hundred thousand tons, and we have more than 4,000 employees. In addition, our company also has other factories in Hunan, Ningxia and Xinjiang.

technical center
Our technical center is over 4,000 square meters and is invested 36 million RMB. In 2005, it was identified as the Tianjin Enterprise Technical Center. In 2014, it was identified as Tianjin Welding Consumable Enterprise Key Laboratory. In 2015, it was identified as a national-level technical center. At present, only two welding consumables companies have national-level technical center in China. We are one of them. In 2017, we set up welding consumables R&D laboratory with Shougang Group Research Institute.
