S+C Group, Germany, provides the technology for high performance rolls in the field of welded tube mills. The company provides the modern designs and expertise for materials and heat treatment in order to determine the optimum roll material and correct hardness for a particular application. There is a wide range of welding processes employed in the manufacture of welded tubes, primarily depending on the tube dimensions and material. These processes include argon arc, laser, plasma, induction, low frequency electric resistance and conductive or inductive high frequency resistance welding. The latter technique is most common in today’s industry. In all cases the rolls need to be manufactured to high accuracy and require a high wear resistance and toughness. Depending on the welding process, the S+C Group is able to supply weld rolls made from different materials including

specially treated Märker  cold work tool steels, hot work tool steels and hard wearing aluminium bronze with non- magnetic properties. This prevents the rolls from becoming too hot by using in high frequency welders.  New weld roll unit made by S+C Bowers & Jones
