損しやすい。[0003] The cost of materials used and the amount of industrial waste cannot be ignored. It requires expensive equipment such as a sintering furnace and cannot be processed at the site of use. At the sintering temperature, the flux burns, so that a flux layer cannot be formed on the weld metal guiding inclined surface or the weld metal guiding groove. Since it is not flexible, it is liable to break when peeled off from the Uranami beat after welding.

できる。Since the present invention is configured as described above, it has the following effects. Material cost is low because only sand, water glass and a small amount of flux are used.
If the used backing material is soaked in water, the water glass dissolves in the water and separates from the sand, so that the sand can be taken out and reused. It does not generate industrial waste because it can be recycled. Since no large-scale equipment is required, even beginners can easily process. Since the flux layer is provided on the welding metal guiding inclined surface and the welding metal guiding groove, the surface of the Uranami beat can be finished smoothly. Since the reinforcing material is embedded, a long packing material can be made.
