Applications and Features |
|
||||||||||
(1) Designed for SESNET (Simplified Electroslag Welding with No-consumable Elevating Tip) of 490 N/mm2 grades steel. (2) The combination of KF-600 and KW-6P will get a weld metal with refined microstructure and excellent mechanical properties. (3) Suitable for shipbuilding, bridge, steel structure, especially good for BOX welding. |

Welding Instruction |
|
||||||||||
(1) Tack welding should be outside of welding part, and keep the gap below 0.5mm. (2) Clean surface of base metal before welding. (3) Keep wire extension at about 30~40mm. |
