摘要
The invention concerns a composite product, also referred to as cored wire, comprising a tubular metal casing having a welt-type seam, containing a core of compacted powder or granular material, which can be easily rolled up and then unrolled, without the risk of the seam coming undone. The composite product according to the invention comprises, on the outside wall of the casing and straddling the seam region, hollow impressed portions which are produced by cold deformation of the metal. These portions are in the form of grooves which are elongate transversely with respect to the axis of the composite product. The composite product according to the invention is used, in particular, for treating metal baths.
