Descrição
Caraterísticas:
LKE-9018-G is high basic offshore electrode according the latest offshore requirements for sub zero temperatures down to -60°C. Suitable for steel types up to 550 MPa yield strength, excellent welding properties and extreme low hydrogen content. The weldmetal is suitable for longer post weld heat treatments as applied in Riser applications.
Aplicações:
It is suitable for the welding of Crane, heavy transport, platforms, vessel and lifting equipment in offshore, pipeline, riser and applications that require NACE requirements (less than 1% Nickel).
Notas sobre a utilização:
1. Dry the electrodes at 350-400℃oc for 60 minutes before use.
2. Take the back-step method at the arc starting.
3. Keep the arc as short as possible.
