Abstract

PURPOSE:To make disappear the carbide at the welded part of the thin circular welded pipe of large diameter of austenitic stainless steel with a little electric power and to perform the solution heat-treatment, by heat-treating the above welded pipe with the high frequency and low frequency induction heating successively and partially to the lengthwise direction.
