Welding Electrode J502, E5003
Welding electrode J502 (E5003) is rutile-calcium based for mild steel and low alloy steel. It could operate on DC/AD, and perform all-position welding. Electrode J502 has excellent welding performance and mechanical properties that enable stable arc, small spatter, easy slag peeling, smooth weld bead.
Application:
Welding electrode J502 is applicable for strength grade 490N/mm2 low alloy structural steel, such as deformed steel bar, 16Mn steel welding.
