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 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.

Purpose:GB E4030 is used for welding of low carbon steel structure and low strength grade of low alloy steel structure. Such as Q235, 09Mnv, 09Mn2 etc.

Six main products series (4.3 million tons)
1. Welding Materials
2. Shipbuilding section
3. High-strength pre-stressed concrete steel bar
4. Forging ingot series
5. Steel ball series for bearing & mining industry
6. Flange & End Plate

As our develop strategy, we have been focusing on the complete production process mode which we deem will bring us synergy, so recently, another new product, i.e. welding consumables will be added to our catalog which will cover all series such as gas-shielded solid welding wire、flux cored wire、submerged arc wire、argon arc wire etc.

We have two main advantages for LT welding wires:
Fully integrated production process, i.e., with the support of upstream world class steel making facilities in house from same group company.
Newly developed production process with latest technology and know-how, i.e., fully automatic production which will be the assurance of quality control.
