ลวดเชื่อมฟลัคคอร์สแตนเลส SOREX : SFC-309MoL
SFC-309MoL is a rutile flux cored tubular wire for all positional welding using pure CO2 shielding gas. It performs with smooth arc transfer, low spatter level, fine ripple, fast freezing slag, easy control of weld pool, good heat and corrosion resistance.
Suitable for welding 22%Cr-12%Ni-2.5%Mo stainless steels and dissimilar metals such as ferritic and austenitic stainless steels, as well as for joining ferritic martensitic steels. It is also used for buffer layers of clad steels.
NOTE ON USAGE :
- Use DC (+) polarity.
- Maintain a higher welding speed in order to get enough penetration in the down hand welding position.
