J501Fe15
Description:
J422 is titanium calcium type carbon steel electrode. AC and DC dual-use, can be all-position welding. Excellent welding process performance and good mechanical properties; stable arc, small splash, easy slag removal, easy re-arc; beautiful weld appearance, welding wave width can be narrow, thin, thick, easy welding, efficiency high.
use:
For welding more important low-carbon steel structure and low strength low-alloy steel structure, such as Q235, 09MnV, 09Mn2 and so on.
