Study of Submerged Arc Welding by Bonded Fluxes (Ist Report)

Properties of Weldment for Stainless Steels

Abstract

Bonded fluxes have been recently brought into the Japanese market by Arcos Corporation. These fluxes are prepared with same manufacture as coated electrodes, and weld metal can be deposited with exact chemical contral. Then, at the results of study, we have also manufactured domestic products of bonded fluxes.
Particularly in this report are described properties of weld metal for stainless steels concerning the domestic product fluxes. The purpose of paper will be briefly writed as follows.
(1) This self-removing slag produces clean weld beads. (2) All deposit metals are excellent against corrosion resistance, impact test in the low temperature and thermal fatigne test. (3) Hot cracking are prevented according to prepared ferrite value in the structure.
