China Manufacturer for Lh Electrode - Mild Steel Welding Electrode J422 E4303 – Tianqiao Detail:
Rutile Type Electrode ISO 2560-B-E4303 A GB/T 5117 E4303
APPLICATIONS:
Used for welding important low-carbon steel structures and low-alloy steel structures with low strength grades, such as Q235, 09MnV, 09Mn2, and etc.
CHARACTERISTICS:
J422 is a rutile type electrode. Can be welding by both AC & DC power source and can be for all-position. It have excellent welding performance as stable arc, little spatter, easy slag removal and reignition-ability etc.
ATTENTION:
In generally, don’t need to re-dry the electrode before welding. When it be affected with damp, should be re-dry it at 150℃-170℃ for 0.5-1 hour.
WELDING POSITIONS:
PA, PB, PC, PD, PE, PF
X-ray flaw detection: Ⅱ level
