AWS E7015-A
Mo Pearlite Heat-resisting Steel Electrode
 Description:E7015-A
is an excellent heat-resisting steel electrodes with
0.5% Mo pearlite low hydrogen sodium type coating. It
should be connected with negative polarity on DC, and
use short arc. Welding can be done in all position.
Before welding ,the welding piece should be heated to
90～100 degree centigrade. After welding, the welding
piece should be reheated at the temperature of 605～635
degree centigrade.
Application:Used
to weld the boiler pipe whose work temperature is under
510 degree centigrade, as well as normal low alloy
high strength steel structure.

Note:
Before welding , it is necessary to clean the work
piece and remove the
impurities such as oil ,grease rust ,moisture, and bake
the electrode at the temperature of about 350 degree
centigrade for one hour.
