EL KADESIA E 12018-G – kadesiawelding

AWS A5.5: E 12018-G

EN ISO 18275-A: E 69 3 Mn2NiMo B 4 5

Description
Basic electrode for vertical-down welding of large diameter pipelines and for structural work. Suitable for filler and cover pass welding in pipeline construction. Deposit is extremely crack resistant, and features high toughness and a very low hydrogen content. Deposition rate is 80 – 100 % higher than for vertical up welding. This stick electrode is optimized for best striking properties and for avoiding start porosity in the cap layer. With its excellent welding properties, the electrode offers easy handling also under difficult conditions. Base Materials EN: L690, API Spec.5L: X100,X110.
