Product Description
LT·J422 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
Welding rods E4303 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.
LT·J422 Conform to Standard GB/T 5117 E4303
ISO 2560-B-E 43 03 A.
Purpose:It is used for welding of low carbon steel structure and low strength grade of low alloy steel structure. Such as Q235, 09Mnv, 09Mn2 etc.
