Que hàn thép carbon Nihonweld N-6027

I. APPLICATIONS:

Horizontal  and flat fillet welding of ships, bridges, structural steels of buildings and general structures.

II. DESCRIPTIONS:

NIHONWELD N-6027 is an iron powder iron oxide type electrode which is designed for providing easy operation in manual welding. As it has excellent re-striking properties, it is suitable for intermittent welding. Extremely high efficient welding can be performed, because its speed ratio is high and its coating contains much iron that adds to the deposit.  

III. NOTES ON USAGE:

·         Adjust the welding current to keep the proper slag covering, because the optimum welding current is subject to the welding process and the surface condition of the steel plate.

·         In the case of manual welding, operate by contact welding.

·         In the case of gravity welding, the optimum speed ratio is 1.2-1.5

·         Dry the electrodes at 70-100 deg C for 30-60 minutes before use. Excessive moisture absorption causes undercuts and irregular beads.
