Applications and Features

( 1 ) Weld metal is ferrite structure with 12%Cr -Ti.

( 2 ) Titanium acts as the stabilizing agent to provide oxidation and corrosion resistance.

( 3 ) Suitable for welding automotive exhausts.

( 4 ) Used to weld Type 409 and 409Ti base materials.

Welding Position

Welding Instruction

( 1 ) Use Ar+1~2%O₂ for spray transfer and Ar+1~2%CO₂ for short-circuit transfer.

( 2 ) For other instructions, please refer to Appendix B and F.
