ENKA Electrodes for High Tensile Steel NK-7016

NK-7016 is a low hydrogen type electrode used for welding of 50 kgf/mm2 high tensile steel. It has excellent usability in all position welding and excellent workability such as good arc stability, smooth beads appearance and excellent slag removal. Its mechanical properties, X-ray qualities and notch toughness are very good and it shows excellent properties in all positions. APPLICATIONS General steel structures, structure of vehicles, storage tanks, boilers, shipbuilding and high-pressure vessels using 50 kgf/mm2 class high tensile steel. INSTRUCTIONS FOR WELDING 1. Dry the electrodes at 350 - 400°C for 30-60 minutes before use. 2. Choose the welding current within the suitable welding current range. 3. Adopt back step method or strike the arc on a start tab to prevent blowholes at the arc starting. 4. Keep the arc length as short as possible.
