Tyd-296 special welding rod for railway rail / tyd-360 rail butt welding rod

  Tyd-296 manganese steel frog welding rod product introduction: tyd296 manganese steel frog welding rod is a new product after kd280 manganese steel frog welding rod, kd296 special surfacing electrode for rail and special electrode for rail
(product executive standard: TB / t1631-2002)
· Jointly developed with Jinhua Institute of Railway Research Institute
· Easy, soft and stable arcing
· Less welding spatter and low smoke emission
· Beautiful weld formation and automatic slag removal after welding
Product parameters: tyd-296 special welding rod for welding repair of manganese steel frog
Break through the high carbon and high manganese formula of the original welding materials and adopt the low carbon and medium manganese formula:
· It reduces the manganese content and smoke emission, reduces environmental pollution and improves the working conditions of welders

· The welding layer metal is single-phase austenite structure, which has the characteristics of post welding surface work hardening, strong impact resistance, good wear resistance and not easy to crack

 
Tyd-360 special welding rod for railway welding repair Product executive standard: TB / t1631-2002
Product features: easy, soft and stable arcing; Less welding spatter and low smoke emission; Beautiful weld formation and automatic slag removal after welding

Tyd-360 special welding rod for rail repair can effectively prevent cracks, head explosion and rail breaking caused by martensite structure after welding; The weld metal has good wear resistance, toughness, strength and other mechanical properties matching with the base metal

 
Tyd-380 special welding rod for rail butt joint executive standard for special welding rod for railway repair: TB / t1631-2002
Product features: easy, soft and stable arcing, & middot; Less welding spatter, low smoke emission, beautiful weld formation and automatic slag removal after welding

Tyd-380 special welding rod for rail butt welding is effectively combined with Cr-Mo-V alloy system and cao-caf2-sio2 slag system, which fills the gap that there is no special welding rod for rail butt welding machine in China
