[CS Electrodes] J422 E4303 Welding Electrode Cs Welding Rod For High Carbon Steel Welding Electrodes
E4303 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
LT·J422
Conform to Standard GB/T 5117 E4303
ISO 2560-B-E 43 03 A
Specification:Welding electrode E4303 (J422) is calcium-titanium coated
carbon steel electrode. It has very good welding uasability
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 propertities give it very good low
temperature toughness.During the application,its characteristic of
easy maneuverabilities 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.
Purpose:It is used for welding of low carbon ssteel structure and low strength grade of low alloy steel structure.Such as Q235,09Mnv,09Mn2 etc.
