The Effect of Heat Treatment on Hardness for Various Submerged Arc Welded Parts

Öz

In industrial applications, the welding of different materials is widely used for taking advantage of the superior properties and reducing the overall costs. While a wide variety of welding methods are used in joining these different materials, the most widely used welding method in the automotive industry, especially in the use of thin sheet designs, is submerged welding. In this study, the application of submerged welding in joining different metals was discussed in detail. The advantages and limitations of the method compared to other welding methods used in joining different metals are given. Various welding procedures that may be an alternative to the method for joining different materials are also included. As an application, 304 grade austenitic stainless steel and St 37 sheet materials were welded under 3 different currents and 3 different designs by submerged welding, and their effects on the hardness values of the weldments were analyzed.
