AWS/SFA 5.4:E2209-16 ,
DIN 8556-86 E2293LR26 EN 1600-97 E2293NLR12
Rutile coated electrode with authentic and ferritic microstructure. The weld metal is resistance to chloride contents media like sea water against petting corrosion as well as crevice and stress corrosion. While welding it is necessary to control heat input which should not be too less too high. Deposited weld are of Radiographic quality.
