Standard: GB/T 5117-1995 E5016 (J506)AWS E7016
Diameter: 2.5*300 mm,3.2*350 mm,4.0*400 mm and 5.0*400 mm
Packing details: 5 kgs/plastic bag in a color box, 20kgs/carton, 1 ton in a pallet
Specification: It is a kind of electrode with low-hydrogen potassium type
coating. AC/DC. All-position welding. It has excellent welding
performance, stable arc, fewer spatters and good slag
detachability. The deposited metal has excellent mechanical
properties, crack-resistance and good low temperature impact
toughness.
Application: Used for welding medium-carbon steel and low-alloy steel
structures, such as 16Mn, 09Mn2Si and A, B, D and E steel for
ships, and also used for welding on thick plates and hard-to-weld
carbon steel structures.

Instructions:
1. The electrodes must be baked under 300~350℃ for an hour before
welding and used as soon as baking is completed.
2. The stains on the weldments, such as rust, oil stains, moisture,
etc., must be cleared away before welding.
3. When welding, short arc must be used and stringer bead is
suitable.
