Welding backing material remade to possess the necessary quality for structural steel!
The "Just Bar SN490B" is a backing material for welding that can be accurately attached to the column without being affected by the precision of the column. By adding protrusions all around, it allows for work to be done at a consistent welding speed compared to those with large protrusions in specific areas. Additionally, the Just Bar has a taper, which improves the bonding of the first layer of welding. 【Features】 ■ Can be accurately attached to the column ■ Allows for work at a consistent welding speed ■ Thin protrusions ensure complete melting, with no issues in ultrasonic testing ■ Ideal for BCR and BCP *For more details, please feel free to contact us.
