Que hàn cường độ cao NIHONWELD N-7014

I. APPLICATIONS:

Welding of ships, railroad vehicles, cars and general structures.

II. DESCRIPTIONS:

N-7014 is a high titania type electrode containing iron powder in its coating and is suitable for all position high efficient welding.

As the contact welding can be performed with this electrode, manipulation of electrodes is easy in horizontal fillet or in the groove.

It is also used in vertical downward welding.

Slag detachability is good and it deposits weld metal of lustrous and good appearance.

III. NOTES ON USAGE:

·         In the case of vertical downward welding, manipulate the electrode, keeping its tip in contact with mother plate as shown in the sketch.

·         Pay attention not to exceed the range of proper currents.Welding with excessive current not only lowers X-ray performance, but also causes increase of spatter, undercut and insufficient slag covering.

·         Dry the electrodes at 70-100ºC for 30-60 minutes before use. Excessive moisture absorption lowers usability and may result in some porosity.
