Gas Welding /span>
Specificationï¼ | AWS | ER80S - Ni1 |
G B | ER55 - Ni1 | |
Shieding Gasï¼ | 80%Ar + 20%CO2 |
Characteristicsï¼
( 1 ) The ER55 - Ni1 welding pan> contains 1%Ni content, it has good plasticity and toughness
( 2 ) Itâs used to weld steel of corresponding strength level, such as ships, bridges, pressure vessels, boilers, etc.
Precautionsï¼
( 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.
