Patentanspruch:Claim: Anwendung des für Rohre mit bei Schweißhitze abschmelzendem Rostschutz bekannten Verfahrens, mit den nicht rostgeschützten Teilen zunächst korrosionsbeständige Vorschuhstücke zu verschweißen, auf Gegenstände aus Stahl oder Eisen, die in ihrer Oberfläche mit Chrom anzureichern und dann mit anderen Bauteilen durch Kaltverformen, z. B. Einwalzen, zu verbinden sind.Use of the process known for pipes with a rust protection that melts when exposed to welding heat, First weld corrosion-resistant front shoe pieces to the rustproof parts, on objects made of steel or iron, which enrich their surface with chrome and then with other components by cold forming, e.g. B. rolling, are to be connected.
