“…Crack formation of laser welded butt joint of AISI304 and Ti6Al4V can be reduced by using copper deposition technique. Presence of copper in the welding interface makes the joint compatible from different point of views [ 148 , 160 , 161 , 162 , 163 ]. Coating can play different role for different laser welding processed for Steel-Mg dissimilar joint.…”

“…For a lap joint configuration, it is cleared from the SEM images that the IMC formations occur mainly in the edges of the weld zone [ 159 , 167 , 168 , 169 ]. The morphological structure of the welding zones i.e., welded zone, heat affected zone and unaffected zone, and topography of fracture surface can be clearly determined from SEM images [ 160 , 161 , 162 , 163 ]. The presence of micro voids and dimples in the fracture zone confirms the ductile mode of the fracture that occurred during the laser welding process.…”

“…The defect-free joint yielded moderate electrical conductivity as compared to copper and steel. Mannucci et al (2018), during laser (Yb:YAG laser) welding of copper and 316L stainless steel, observed that high laser power led to hot cracking at the weld zone. They also concluded that the level of copper penetration significantly reduced the corrosion resistance of the welded joints Copper penetration at the weld zone was also observed by Moharana et al (2020) during laser welding of copper and AISI 304 stainless steel.…”

Copper-steel welded joints are now used widely in heat exchangers, piping and power generation industries. Owing to their different thermal characteristics, sound welding of the pair is a challenging task. Extensive research is carried out to achieve successful welding of copper and steel. This article presents an insight into the works done on the joining of copper and steel by various techniques. The microstructural modifications in different approaches are critically presented. Mechanical properties of joints obtained through different techniques are compared.

“…8 Lack of fusion and hot cracks were observed at weld interface and evaluated tensile strength of the joint was 225 MPa. 8 Among the various available techniques for joining dissimilar materials, laser additive manufacturing (LAM) is one of the advanced techniques for building multi-material components and dissimilar joints. Generally, LAM is divided into two broader categories: powder bed fusion (LAM-PBF) and directed energy deposition (LAM-DED).…”

Laser additive manufacturing using directed energy deposition (LAM-DED) technique is one of the recent techniques for fabricating engineering components directly from 3D CAD model data using high power lasers. In this respect, LAM-DED of copper (Cu) and stainless steel (SS) is an enduring research area. However, LAM-DED of Cu is challenging due to higher thermal conductivity, lower absorption to infrared radiation and oxide formation tendency. The present work reports an experimental investigation to evaluate the effect of process parameters on the track geometry, contact angle, inter-diffusion and micro-hardness of Cu tracks deposited on SS 304L substrate using LAM-DED. Analysis of variance is used to estimate the contribution percentage of process parameters on the track geometry. Further, Cu bulk structures are deposited at an identified combination of process parameters and they are subjected to optical microscopy for microstructural characterisation. Further, finite-element-based numerical simulation is performed to understand the temperature distribution during the processing of Cu bulk structures on SS304L and the temperature results are co-related with the microstructural transformation during the processing. This investigation paves a way to understand the effect of processing parameters for building Cu bulk structures on SS Substrate using LAM-DED.
