Applications
Welding of aluminum-killed steel and 2.5% Ni steel used for machinery and equipment for low temperature
Characteristics
N-8016-C1is an all position extra low hydrogen type electrode type electrode for aluminum-killed steel and 2.5% Ni steel used for machinery and equipments for low temperature (lowest-60°C) is obtained because the weld metal contains about 2.5% Ni. N-8016-C1 also provides good X-ray soundness and good usability.
Notes on usage
(1) Pay attention not to exceed proper heat-input causes deterioration of impact values of weld metal.
(2) Preheat at 50-100°C. The temperature varies in accordance with the plate thickness and steel kind.
(3) Dry the electrode at 350-400°C for about one hour before use.
(4) Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting.
(5) Keep the arc as short as possible.
