SF-65A is a seamless rutile all position flux-cored wire developed for welding high tensile steel such as s550 and similar high tensile strength steel. The wire is to be used with a M21 Argon/CO2 mixed shielding gas, which ensuring a user friendly and stable arc with minimum spatter and good transition to the parent material. Due to its seamless characteristic, the wire has an extremely low content of hydrogen (typical <3ml/100g weld metal), something which ensures low risk of cold cracks.
The wire is copper coated and has a clean surface with exact diameter and perfect roundness ensures a stable and even wire feeding as well as easy handling and storage procedures. The stick out should be between 15-20mm depending upon welding parameters. Volts should be app’x 10% of the Amperage, this is about 1-3 volts lower than a conventional folded flux cored wire.
Diffusible hydrogen content (ml/100g):
≤5 ml/100g (2,8 ml/100g typical).
