Welding Electrode J422, E4303
welding electrode E4003, J422

 



Welding electrode E4303 (J422) is rutile-calcium based carbon steel welding electrode. It has excellent welding performance and mechanical properties that enables to operate on AC/DC, perform all-position welding. It is featured with stable arc, small spatter, easy slag peeling and arc re-striking. Weld bead is smooth and clean. It is flexible in weld ripple width and thickness.


Application:


Electrode J422 (E4303) for carbon steel and low strength grade low ally steel, such as Q235, 09MnV, 09Mn2, etc.
