Que hàn thép carbon Nihonweld N-6012

 I. APPLICATIONS:

Mild steel fabrications, Steel windows and iron grills and fences, container steel, welding of ungalvanized pipes, steel structures for houses, steel chairs and tables, steel ladders and other light gauge mild steels and others.

II. DESCRIPTIONS:
An all position general purposed Shielded Metal Arc Welding electrode with good fusion characteristics and penetration. Well suited to bridge gaps on poor fit-up jobs. Handles easily on light sheet metal as well as on heavy steel structures. Weld has smooth, well-rounded and even beads with closely rippled surface. The fillets are convex without undercutting. Its all-positional operability, combined with a fast freezing weld metal and a forceful arc makes it an ideal electrode for workshop and site conditions. Excellent deposition characteristics when welding both vertically-up and vertically-down. The slag comes off very easily and is in most cases self-releasing.

 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 degrees 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.
