PP – 1DSK
Flux – cored wire for welding
The flux – cored wire of PP-1DSK grade is used for mechanical welding of metal structures from low-carbon steels St3, St4, 09G2, with thickness more than 3 mm. The weld position is down. The metal can be coated with scale and little layer of rust. Stability of arc is high. The separability of slag is excellent. The wire is produced according to TU U 23165028-002:2005.
