HF-ERW High-Frequency Electrical Resistance Welding of austenitic stainless steel tubes method for producing

摘要

In the present invention, in manufacturing an austenitic stainless steel pipe using high frequency welding, it prevents roll scratch defects occurring on the surface of the steel strip during the forming of the tube, and the protruding weld bead generated from the inner and outer surfaces is accumulated on the cutting edge of the bite ( In order to enable continuous production by preventing build-up), conventional high frequency electric resistance welding (HF-ERW) is characterized by including a step of applying lubricant to the surface of the steel strip before molding and cooling the inner and outer bead cutting bite. This is a method of manufacturing an austenitic stainless steel pipe that could not be produced.
