AA 307 FCAW Flux-Cored




AA 307

 
CATEGORY 
TYPE 
Rutile fluxcored stainless steel welding wire for dissimilar welding and buffer layers
APPLICATIONS 
Welding stainless steel to low alloyed steels (dissimilar welds), buffer layers before hard facing, rails crossings, armour plate, austenitic manganese steels and other difficult to weld steels.
PROPERTIES 

Smooth drop transfer and stable arc with no spatter losses. Excellent productivity and weldability, better wetting properties compared to solid wires. Excellent weld metal quality and X-ray soundness. Post weld heat treatment (PWHT) can be applied without any problems.
