FIELD: technological processes.
SUBSTANCE: invention can be used in restoring worn workpieces by contact welding of welding filler. Container in the form of a rectangular parallelepiped is made of woven steel mesh. Base of the container corresponds to the area of the surface to be restored, and the height is 2–3 times higher than the required thickness of the coating. Container is filled with a filler powder, the granule size of which exceeds the gaps of the container mesh. Filled container is pierced through with steel wire in two directions – along and across the base. Piercing step is equal to the width of the working surface of the roller-electrode.
EFFECT: use of the pierced combined filler allows forming a uniformly thick metal coating without unevenness on the surface to be restored.
