Effect of welding electrode variation on dissimilar metal weld of 316l stainless steel and steel ST41

Abstract

The propeller shaft is part of the ship which transmitting rotation from engine to propeller. The shaft is also used in small-medium size of fisherman boat. In order to reduce the cost of production, dissimilar metal bases are used by joining Steel ST41 and 316L Stainless Steel in process. This research was conducted to analyze effect of welding electrode towards tensile strength, macrostructure, and microstructure of Steel ST41 and 316L Stainless Steel welded metal. Two variations of electrode that used in this paper were E309-L and E6013 with Shielded Metal Arc Welding process (SMAW). The other parameter such as current was set at 80 A and voltage was set at 20 V with 20 mm/min welding travel speed. The results of tensile test show average tensile strength max (σmax) of E309-L and E6013 electrode were 581,42 MPa and 599,24 MPa respectively. These results show that welding process is increasing the maximum tensile strength from base material strength level. The microstructure test interpretation shows E309-L electrode has lower possibility to create delta ferrite in HAZ (Heat Affected Zone) rather than E6013 electrode. This means welding process with E6013 tends to have lower corrosion resistance.

Analysis of hardness for dissimilar stainless-steel joint by mathematical modelling

“…(A-TIG) shows that joint has a decent combination of tensile strength and impact toughness [28]. The propeller shaft made by joining steel ST41 and 316L stainless steel with a variety of electrode in SMAW process the result of the analysis shows that the tensile strength of the base material increases and use of E6013 electrode has lower corrosion resistance [29]. Micro-structure and corrosion behavior of copper and 316L stainless steel welded joints on an electrolytic copper cathode plate was investigated.…”

Research Gap Finding in Shielded Metal Arc Welding of Steel

“…As a result, these factors make the weld vulnerable to issues such as corrosion, fatigue cracking, grain enlargement, microstructural changes, and variations in hardness levels within the welded area. Consequently, these factors can weaken the strength of the welded joint [10]- [13]. To achieve a strong and durable weld joint, it is crucial to ensure excellent metal fusion and select appropriate welding parameters [9], [14].…”
