“…Components with adequate ductility, high strength, good corrosion resistance, and desirable electrical and thermal conductivities have been achieved through DM welding [3,4]. Several DM welding techniques have been reported, including Welding-Brazing [5][6][7], Arc [8][9][10], Friction [11], Friction stir [12,13], Ultrasonic [14,15], Explosive welding [16], Laser [17][18][19], and Hybrid Laser-Arc welding [20,21].…”

Abstract:In this study, an attempt on pulsed-fiber laser welding on an austenitic-duplex stainless steel butt joint configuration was investigated. The influence of various welding parameters, such as beam diameter, peak power, pulse repetition rate, and pulse width on the weld beads geometry was studied by checking the width and depth of the welds after each round of welding parameters combination. The weld bead dimensions and microstructural progression of the weld joints were observed microscopically. Finally, the full penetration specimens were subjected to tensile tests, which were coupled with the analysis of the fracture surfaces. From the results, combination of the selected weld parameters resulted in robust weldments with similar features to those of duplex and austenitic weld metals. The weld depth and width were found to increase proportionally to the laser power. Furthermore, the weld bead geometry was found to be positively affected by the pulse width. Microstructural studies revealed the presence of dendritic and fine grain structures within the weld zone at low peak power, while ferritic microstructures were found on the sides of the weld metal near the SS 304 and austenitic-ferritic microstructure beside the duplex 2205 boundary. Regarding the micro-hardness tests, there was an improvement when compared to the hardness of duplex and austenitic stainless steels base metals. Additionally, the tensile strength of the fiber laser welded joints was found to be higher when compared to the tensile strength of the base metals (duplex and austenitic) in all of the joints.

“…Figure 14(c) reveals cleavage pattern as well as dimples at various locations; this indicates that the fracture may have occurred by the mixed phenomenon i.e. quasi cleavage fracture mechanism (Handa & Chawla 2014a). Figure 14(d) and (e) represents dimpled pattern showing ductile fracture.…”

In the present study an attempt was made to join austenitic stainless steel (AISI 304) with low alloy steel (AISI 1021) at five different rotational speeds ranging from 800 to 1600 rpm and at as many different axial pressures ranging from 75 MPa to 135 MPa and then determining the strength of the joint by means of tensile strength. Furthermore scanning electron microscope analysis was performed to evaluate the pattern of failure at the fractured locations, also the micro hardness was checked at the weld interface and at distances on either side of the weld joint to evaluate the effect of heat. The highest tensile strength achieved by the welded specimens was 1.8% higher than the AISI 1021 steel and the lowest tensile strength obtained was 20% lower than the parent AISI 1021.

“…When the forge pressure is applied the grains became finer, voids became narrower, and are eliminated at the abutting surface due to the local heat added up on the interface region. Thus the tensile strength is much higher in the interface due to the fine grain development of applying forge pressure [13] . The low tensile strength 483 MPa was found in sample S1 with friction pressure of 60 MPa and forging pressure of 90 MPa.…”

In this paper, standard SS304 austenitic stainless steel and SS430 ferritic steel cylindrical rods were fabricated by friction welding process by varying the frictional pressure and forge pressure in order to understand the effect of process parameter. The tensile strength and Vickers micro hardness tests were conducted for each fabricated joint to evaluate the mechanical properties of the welded specimen. It was found that sample S5 with friction pressure of 90 MPa and forging Pressure of 120 MPa has the high tensile strength value of 637 MPa and 372HV at the interface region. A detailed microstructural analysis was performed at the interface to reveal interconnecting of dissimilar metals.
