AWS E7015-A
Mo Pearlite Heat-resisting Steel Electrode
 Description:AWS 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.
