Applications
Welding of 0.5% Mo heat resistant steel, pipes and pipelines such as API 5LX-x52~x60.
Characteristics
N-7011-A1 is a high tensile strength steel cellulose coated electrode for all-position welding.
Heat resistance of the weld metal is excellent.
Slag removal and bead appearance are good.
Notes on usage
(1) Pay attention not to use the currents exceeding the recommended currents, because the proper currents for cellulose type electrodes are lower in comparison with those for ordinary type electrodes.
(2) As this electrode is prone to absorb moisture, store it with care.
(3) Dry the electrodes at 70-100ºC for 30-60 minutes before use.
