80S-Ni -1 is used for welding fine-grain and low-alloy nickel steels to produce high impact values even at low temperatures such as -50° F.
AWS ER80S-Ni1 is a filler metal that is often used in submerged arc welding (SAW). It is classified as an "80" series filler metal. The tensile strength is 580 MPa. The "S" in the name stands for "steel," and the "Ni1" indicates that it contains a small amount of nickel (less than 1%).
AWS ER80S-Ni1 is used to weld low-alloy steel and can be used in all welding positions. It is commonly used in the construction of pressure vessels, storage tanks, and other structures that are exposed to high levels of stress. It is also used in the petrochemical and power generation industries.
In general, the selection of a filler metal for SAW should be based on the base metal properties, the welding position, the service environment, and any code or specification requirements.
( 1 ) The product contains 1%Ni content, it has good plasticity and toughness
( 2 ) It’s used to weld steel of corresponding strength level, such as ships, bridges, pressure vessels, boilers, etc.
( 1 ) Adequately clear the oil,rust,moisture,dust and other debris of the welded parts.
( 2 ) When heat input is too big, it can reduce impact value , so welder should pay attention to the choice of welding current.
