摘要： An auger composed of an auger body integrally formed with a spiral blade and at its opposite ends with a pair of shaft portions is manufactured by the steps of forming annular recesses on the shaft portions in a cutting process, building up an anti-abrasive and anti-corrosive alloy by plasma-arc welding in the annular recesses of the shaft portions and finishing each built-up portion of the alloy in a grinding process to form a journal portion on the respective shaft portions of the auger, wherein precipitation hardening stainless steel used as a base metal of the auger body is preheated for a predetermined time prior to the steps of plasma-arc welding of the alloy. In this manner, the stainless steel body is subjected to an aging heat treatment caused by (a) the preheating and (b) the subsequent welding heat generated during the plasma-arc welding process.
