welding electrode

Used to weld middle carbon steel and low alloy steel structure
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
