A brief review on welding of stainless steel clad plates

May 08, 2021 · Stainless steel clad plates have been gradually applied in the areas required for both good mechanical properties and corrosion resistance effects, but welding technology is still playing a limiting role in its further large-scale application. The aim of this paper is to review the welding status and future prospective of stainless steel clad plates so as to offer a basis for following research.

Dissimilar joining of AISI 304/Q345 steels in keyhole

Mar 17, 2018 · Keyhole tungsten inert gas welding (K-TIG) was used to join AISI 304 stainless steel with Q345 low-alloy steel of 8 mm thickness in a single pass. Welding formation and process windows in different welding speeds were discussed. Microstructure and welding properties of dissimilar joints were investigated. The results show that in a relatively high welding speed (more than 300 mm/min), high Effect of Welding on Microstructure and Mechanical welding of low carbon steel, there are limited publica-tions [2-8]. For example, Gural et al. [2] have studied the heat treatment in two phase regions and its effects on microstructure and mechanical strength after welding of the low carbon steel. On the other hand, Eroglu and Ak-soy [3] investigated the effect of initial grain size on mi-
