E5003 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
E5003 is calcium-titanium coated carbon steel electrode. It has very good welding usability that enables it to operate on AC/DC, performs all-position welding, has stable arc, removal of slag is easy and has good bead appearance. Its good mechanical properties give it very good low temperature toughness. During the application, its characteristic of easy maneuverability offers easy striking, easy re-striking and good control of welding speed, which enables the welders to have desired weld path and penetration of the arc.
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.
