AWS E7016
Mild Steel Electrodes
 Description:E7016is
of carbon steel electrodes with low hydrogen potassium
type coating .The weld mental has superior mechanical
properties and high crack resistant properties It can
be welded on both AC and DC. Welding can be done in
all position. When used AC, the stability is inferior
to that used DC.
Application:Used
to weld middle carbon steel and low alloy steel structure,such
as 16 Mn,09Mn2Si etc.

Note:
Before welding, it is necessary to clean the work
piece and remove the impurities such as oil ,grease
rust and moisture, bake the electrode at the temperature
of about 350 degree centigrade for one hour. The welding
must be carried out under short arc and is suitable
for narrow path.
When used DC, the electrode must be connected with
positive polarity.
