CLASSIFICATION
AWS/SFA 5.1 E7018-1, DIN 8529
ESY 4276MU8 DIN EN 499 E426B42H5 BS639-86 E5143B(24H)
DESCRIPTION
A basic coated, hydrogen controlled electrode deposits tough and crack free weld metal in butt and fillet joints. The weld metal has a very low diffusible hydrogen content and is resistant to ageing. The electrode has an extremely stable arc which enables it to be manipulated in the most difficult positions without any risk of arc extinction due to freezing. The deposited welds meet X-ray quality requirements.
