Que hàn thép carbon Nihonweld N-13

I. APPLICATIONS:

Welding of all types of mild (low carbon) steel such as:

·         Steel structure-trusses, portal frames, tubed framework

·         Sheet and plate metal structures and containers-plating, storage tanks, hoppers, silos, bins

·         General Steel fabrication & assembly job

·         Welding of jeep, auto bodies & vehicles

·         Welding of farm and agriculture equipments, fences, farm tools, etc.

·         Light steel frames - grills, ornamental and gate works, furniture

·         General workshop welding and maintenance

·         Compatible and suitable for welding steels to:

ASTM (eg. A36)

BS EN 10025 (eg. S275, S275 JR) BS 4360 (eg. Grade 40, 43) API Std. 5L (eg. Grade A, B, A25, X42, X46) JIS G3106 (eg. SS41, SM41)

II. DESCRIPTIONS:

N-13 is a medium thick coated rutile electrode for welding light & medium fabrications. It has the following special features.

III. NOTES ON USAGE:

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

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

·         Excessive drying before use causes less in penetration and overheating of the electrode.
