AWS E7016
DESCRIPTION:
AWS E7016 is a potassium low hydrogen type carbon steel welding electrodes.It can be used for all position welding with excellent performances: small spatters,easy restrike arc,high welding efficiency,fine appearance and slag easy to remove,etc.The weld seam metal shows a satisfactory plasticity,excellent low temperature toughness and high crack resistance.
APPLICATION:
Suitable for welding important carbon steel and low alloy steel,such as 16Mn steel and ships fabricated by A,B,D,E grade steel.
ATTENTION:
a. Welding electrodes should be baked for an hour at the temperature of 350℃ before welding.
b. Short arc and narrow weld are recommended in welding.
c. Before welding.the weld metal must be cleared away impurities,such as rust,oil,moisture,etc.
