Lastifil 20TR is a rutile cored copper coated seamless wire for welding unalloyed and low alloyed steel (up S355) with gas protection.
Very good weld ability and smooth aspect.
Slag can be removed easily.
Extra low hydrogen content (<5ml/100 gr.).
Can be used to weld steel that is rusty or coated with primer.
Welding steel: S235, S275, S355.
Boiler plate: P235GH, P265GH, P295GH (EN 10028-2).
Hull steel grade A, B, D, E, AH32 - EH36.
Fine grain steel: StE355 - StE460 (EN 10028-3).
Use a stick out of 20 to 25 mm (0.8-1 inch) in function of the diameter.
Before welding a second layer, slag must be removed from the previous layer.
