Comparative Evaluation of Mechanical Properties and Micro Structural Characteristics of 304 Stainless Steel Weldments in TIG and SMAW Welding Processes

Abstract

Abstract

Electric current effect on mechanical properties of SMAW-3G on the stainless steel AISI 304

“…Often the welding process must be done in a certain place because it is formed from a construction, such as the welding of the pressure pipe connection that must be buried in the ground or welding on the corner of the building, on the ceiling, ect. so that required different welding position [7]. Given the necessity of a particular welding position, it will give different results to the strength and hardness of welding results…”

Effect of SMAW process parameters on similar and dissimilar metal welds: An overview

“…( Karthik et al., 2013 ) investigated the effect of input process variables on mechanical, microstructural and morphological characteristics of most common grade i.e stainless steel 304 using gas tungsten arc welding and shielded metal arc welding. The size of material plate was 200 × 150 × 6 mm and electrode used is (SS E308L).…”

Mechanical Properties and Microstructural Analysis of 304 Stainless Steel by TIG Welding

“…Commonly, the application were applied in heavy engineering field such as aircraft frames, automobile parts, railway wagon and many more [2]. The product from welding application exhibit good mechanical properties and manufacturing characteristic.…”

“…The usage of stainless steel is small compared to carbon steels but exhibits a steady growth. The important thing about welding a stainless steel were the quantity of ferrite in the welds must be minimized or controlled to avoid degradation during its lifetime service [2]. However, there are several factors that will change the behavior of the welding strength when some welding parameters were being altered.…”
