J107Cr
Description:
J502WCu titanium calcium type coating is low alloy weathering electrode. AC and DC dual-use, can be all-position welding. Has excellent welding performance and mechanical properties, stable arc, spatter, easy slag removal; weld appearance, deposited metal has good resistance to atmospheric corrosion.
use:
The electrode is a special electrode for weathering steel, dedicated to the weathering of the railway rolling stock welding, such as 09MnCuPTi steel structure welding.
