Effect of Weld Process Parameter on Weldability and Corrosion Behavior of Ferritic Stainless Steels: A Review

The impetus nickel supply shortfall and incessant change in its expense brought about getting the consideration of specialists to affect different options of stainless steel which contains less measure of nickel as its alloying component. Among the different existing stainless steel grades, austenitic stainless steels (ASS) are used in roughly 60-70 % of uses, yet ASS requires nickel as its major resulting. One of the better choices to supplant austenitic stainless steel is ferritic grades, which contain less nickel and have very much like execution at a generally lower cost. The current investigation is an endeavor to feature the different welding strategies (fusion/solid-state) which are used most, for the joining of these ferritic stainless steel (FSS) grades. The writing affirms that because of the metallurgical issues related to fusion welding processes, solid-state joining processes, for example, forge welding, pressure welding, ultrasonic welding and friction stir welding (FSW), and so forth are educated to be utilized for joining concerning ferritic stainless steels depending their appropriateness. Furthermore, the corrosion-related perspectives should likewise be dealt with during the utilization of these prepares for different purposes.
