Applications and Features

(1)  Designed for SESNET (Simplified Electroslag Welding with No-consumable Elevating Tip) of 550 N/mm² grades steel.

(2)  The combination of KF-600 and KW-80 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.
