Introduction:

E7016 is a low hydrogen potassium type carbon steel electrode.both AC and DC, It Can be used for all position welding.It has very good welding usability that enables it to perform all-position welding, has stable arc, removal of slag is easy and has low spatter. the deposited metal has good mechanical performance and crack-resistance, which offers good low temperature toughness.

Uses:

E7016 is applied in welding medium-carbon steel and low-alloy structures such as 16Mn, 09Mn2Si and the steels used in shipbuilding such as A, B, D, E. It is also used in thick steel plates and the carbon steel structures that are difficult to weld.

Notes:

1. the electrode must be preheated at the temperature of 350C for 1 hour. Preheat the rod whenever it is used.

2. the impurities such as rust, oil stains and moisture must be cleared off of the work piece.

3. Short arc is required to perform welding. Narrow weld path is preferred.
