bercoweld® B10

bercoweld®  B10 is used for buildup welding on cast iron. Especially suitable for welding deep drawing sheet steel (like body panels). With this welding filler, wide seam gaps can be bridged due to its good flow properties. Very suitable for oven soldering.

Pulsed power welding is recommended. Preheating the base material is generally not required.
