Laser butt welding of thin steel sheets without filler material was widely used in many industrial fields. However, it was very difficult to focus the small laser spot on the narrow gap between the sheets during the laser butt welding process. In this study, a new method to weld thin steel sheets using a high-speed laser cladding technique is proposed. Stainless steel sheets with a thickness of 0.5 mm were welded using the high-speed laser cladding process. The results illustrated that good weld joints could be obtained without obvious cracks and pores in most of the specimens. The joints were well formed even if the sheets were not spliced together entirely. The average tensile strength of the specimens was about 500 MPa, which is almost the same as that of the substrate. The results also showed that most of the failures did not happen in the welding region, which could be concluded that the strength of joints was higher than that of the substrate. The microstructure was determined using an optical microscope (OM) and scanning electron microscope (SEM). The results showed that it may be a good choice to use the high-speed laser cladding technique for butt welding of stainless steel sheets.

“…This can help to improve the weld quality and reduce the risk of overheating. However, there are still significant gaps that need to be addressed, including comprehensive studies, standardization of surface characterization methods [35], Understanding the strength of the joint has been done by researchers, they conducted parameter research by testing the shear tensile strength, It is very important to optimize welding parameters, in order to obtain optimal joints [7], and environmental impact considerations. Addressing these challenges will lead to better weld joint quality, enhanced joint performance, and more sustainable DMRSW practices in various industrial applications.…”

Resistance spot welding plays a critical role in the manufacture dissimilar material industry. However, there are differences in mechanical properties between mild steel and satinless steel so as to reduce the quality of welded joints. In order for differences in mechanical properties to be corrected, surface roughness was treated. The aim of this study was to optimize the welding parameters of DRSW with surface roughness by analysis using the Taguchi and Anova Methods. In this study discusses about investigates the Resistance spot welding parameters on weld geometry, mechanical properties, and SEM EDS on dissimilar materials of mild steel and stainless steel. The material thickness of the mild steel and stainless steel are 1 mm, respectively. The process parameters of the resistance spot welding joint used, example; surface roughness, current, welding time, and electrode force. Quality welding joint test results include weld geometry, mechanical properties, and SEM EDS. Weld geometry testing to determine the weld nugget profile. The mechanical properties test was shear tensile test, while the SEM EDS included macrostruture and microstructure observations. The results showed the highest nugget diameter 6.65 mm highest shear tensile strength 7.66 kN. The most influential parameter is current by 75.08 %, then surface roughness by 12.35 %. The highest tensile strength has fewer defects. Surface roughness treatment before welding is very good to make welding quality joints between mild steel and quality stainless steel increase. Surface roughness treatment was very good to be included when making welding procedures for welding engineers for welding processes resistance spot welding dissimilar mild steel with stainless steel.
