Effect of the welding method on the structure and properties of welded joints in dissimilar steels

Abstract

Influence of pulsed-arc welding condition values and of electrodes OZL-8, NIAT-5, and EA-395/9 on the structure and properties of two-layer steel (12Cr18Ni7Ti steel) is studied. The most significant parameters influencing the welded joints' properties are established. On the base of the welds' bend angles analysis, optimal pulsed-arc welding conditions and an electrode type are determined for two-layer steel welding.
