Abstract:
A method for manufacturing a profile clamp for joining flanged components, said profile clamp being at least partially circular and having conical side walls that are bent radially inwardly, said profile clamp being made of martisistatic steel having, at an ambient temperature of 20Â° C. to 750Â° C., a coefficient of thermal expansion that is lower than a coefficient of thermal expansion of a ferritic casting material by at least 0.3Ã—10âˆ’6 m/mÂ° C., said method comprising the steps of:prequenching and tempering a strip of said steel; forming a clamping band of said profile clamp by shaping and welding said strip to produce at least one welded area; and induction tempering said at least one welded area.
